Key Takeaways at 12 Weeks Pregnant

Those overwhelming first-trimester symptoms may begin to wane. That means morning sickness may start fading soon and the outrageous exhaustion-fog may lift. Hope is on the horizon!
Have you bought maternity pants yet? If not, it’s time to loosen your purse strings—and your belt. Your belly is expanding and a budding bump is probably visible at this point.
Baby continues to develop by leaps and bounds every day. Their fingers and toes are no longer webbed, and their eyes, nose and fingernails are forming—so cool!
Getting a 12-week ultrasound? Your tech might be able to determine the sex of baby at this point, but it’s not guaranteed, nor is it foolproof.

Things are changing fast at 12 weeks pregnant. You’re reaching the home stretch of the first trimester (we know, finally!), which means your hormones are likely to tone things down a bit. It also means you may be ready to share your pregnancy news with family and friends. So exciting!

Watch Week 12 Highlights

Baby at Week 12

Your 12-week fetus is almost done developing their body’s important systems and parts, which means it’s all about getting bigger and more mature from here on out. Yep, baby's about to enter the growth and maturation stage, in which organs and tissues will grow and develop rapidly.

Baby at 12 weeks is opening and closing their fingers and curling their toes, and their brain is developing fast!

Baby is now developing reflexes—if you poke your 12-week pregnant belly while looking at baby on an ultrasound, you'll likely see movement. If you’re 12 weeks pregnant with twins, your twosome is developing at a similar rate as singleton babies at 12 weeks. Later on, they’ll have a slightly slower rate of growth.

How big is baby at 12 weeks?

At 12 weeks pregnant, baby is as big as a plum. The average 12-week fetus is about 2.1 inches long and .49 ounces. Now that baby's got pretty much all of their important organs, their main job is to keep on growing. Go, baby, go!

12 weeks pregnant is how many months?

At 12 weeks pregnant, you’re about three months pregnant. Remember, pregnancy is 40 weeks long, which doesn't break down cleanly into nine months. Just two more weeks until you can officially put your first trimester behind you!

12 week ultrasound

You may have one more prenatal checkup before the end of your first trimester. Whether or not you have a 12-week ultrasound may depend on your doctor’s preference and maybe also on what your insurance covers. If you do get an ultrasound at this time, you’ll notice that you can see your 12-week fetus more clearly this time around, which may make you want to start spreading the news that you’re expecting.

Itching to find out if it’s a boy or a girl? We hate to be the bearers of bad news, but on a 12 weeks pregnant ultrasound, the sex isn’t usually revealed. Between 12 and 13 weeks is the very earliest a boy or girl could possibly be seen on an ultrasound, and the anatomy is still difficult to make out with any certainty. Your OB or technician is much more likely to be able to see baby’s sex at the mid-pregnancy anatomy scan, which will happen around week 20. However, if you received DNA blood testing for chromosomal disorders, you may find out baby’s sex when you get those results—if you want to know, that is!

Around week 12, you might want to know more about baby’s health, so you may have genetic testing done to determine the risk of birth defects or other problems. This can be a little scary—and confusing—so be sure to ask your OB plenty of questions, and know that it’s much more likely that baby is a-okay than anything else.

What does a 12-week fetus look like?

With the first trimester almost done, you may be wondering, “what does a 12-week fetus look like?” New and exciting changes are happening for baby at 12 weeks! The eyes and nose take shape, fingers and toes lose their connective webbing, fingernails develop, teeth buds crop up and organs such as the kidneys and intestines keep growing.

Pregnancy Symptoms at Week 12

Here’s the good news about 12 weeks pregnant symptoms: Morning sickness and fatigue may start to fade a bit soon as your hormones start to calm down. The bad? Headaches and dizziness may replace them. We’ll take that trade-off. Here’s more info about what’s happening to your body at 12 weeks pregnant:

Increased discharge

This clear discharge might seem weird, but it’s normal and has an important purpose: to protect your vagina from infection. But if you have yellow, greenish, pink or brown discharge during pregnancy week 12, call your doctor right away. Those colors could be a sign of infection or even miscarriage.

Spotting

Spotting or bleeding during pregnancy at 12 weeks could be worrisome—or it could be nothing at all. For example, your cervix is more sensitive during pregnancy, so simply having sex could cause light bleeding that’s harmless. If you’re spotting or bleeding, definitely tell your doctor. If the bleeding is accompanied by cramping or the flow is heavy, it’s an urgent call.

Headaches

These may start to intensify around week 12 of pregnancy. Headaches may be caused by hormonal shifts, drops in blood sugar, dehydration, lack of sleep or stress. To deal, pay attention to what might be triggering your headaches and try to avoid those culprits. If you notice a drastic increase in headaches or a type of headache you’ve never experienced before (such as a migraine), or if your headaches are accompanied by other weird symptoms, let your OB know.

Dizziness

Whoa! Hormone shifts and blood pressure changes could cause dizzy spells around pregnancy week 12 (and sometimes even earlier!). You can help prevent dizziness by snacking regularly, avoid becoming overheated and drinking plenty of water. Sit or lie down if you’re feeling dizzy or lightheaded and let your doctor know about any severe bouts.

If you’re 12 weeks pregnant with twins, you may still be experiencing morning sickness, while your singleton mom-to-be counterparts are likely starting to see the light at the end of the nausea tunnel. Know that things will likely improve soon.

What should I be feeling at 12 weeks pregnant?

Your body is working hard, and you may wonder, “what should I be feeling at 12 weeks pregnant?” You may not be showing much on the outside yet, but on the inside everything feels like it’s changing! In addition to typical 12 weeks pregnant symptoms, you may start to feel shifts with morning sickness and fatigue. One day you might be exhausted, and another you may feel a burst of energy, while nausea comes and goes. Hang tight—you're getting closer to the second trimester! Make sure you get plenty of fluids and healthy foods for those days when morning sickness makes it rough to keep anything down.

Your Pregnant Belly at 12 Weeks

At 12 weeks, your pregnant belly is probably getting noticeable now. This is one reason many moms-to-be start to tell others they’re expecting around 12 weeks. (Of course, if you’re 12 weeks pregnant with twins, you may have been showing for weeks now, obviously because you’ve got double the babies in there!)

If you haven’t already, start taking photos of your pregnant belly at 12 weeks. Trust us, after pregnancy you’ll want a memento of how much your body changed throughout.

How does your stomach feel at 12 weeks pregnant?

You may already feel the waistband of your clothes getting tighter as your stomach begins to round out. When baby is at 12 weeks, your uterus is expanding to make room for your growing little one. This can also cause a tight feeling in your stomach itself as the stretching uterus puts pressure on the surrounding tissues of your body. Gas or constipation are other common causes of tummy troubles.

You're moving for two! Going for a walk, doing your favorite workout or dancing to music creates better weight management, cognitive development, cardiovascular health and beneficial health outcomes for baby. Remind yourself on your exhausted days that exercising through your pregnancy is going to make this journey easier for you and set baby up for a lifetime of better health!

Tips for 12 Weeks Pregnant

Here’s some advice for living your best pregnant life as you finish up your first trimester and move into your second.

Give sore breasts some TLC

Your body’s hormones are getting you ready for breastfeeding, which can make breasts sore or tender. Soothe pain by wearing comfortable clothes that don’t irritate the body, trading in underwire bras for maternity or nursing bras with soft support or using ice packs for temporary relief.

Wear sun protection

One 12 weeks pregnant symptom that can occur for many women is melasma, or the “mask of pregnancy,” where dark spots appear on the face. It’s caused by those active hormones, but melasma can be made worse with sun exposure. Protect your skin with a mineral-based sunblock and a wide-brimmed hat, and stay in the shade or indoors during the day whenever possible.

Don’t give into junk food temptations

If your appetite starts to return as morning sickness fades, don’t feed it with lots of sugar, fats or processed foods. Healthy eating is good for you and baby, and it also helps you achieve a healthy weight gain moving forward. While it’s totally normal to not gain any weight in the first trimester (or even lose a few pounds), women of normal pre-pregnancy weight should plan on adding a pound or two a week during the second trimester

Think about getting physical

Pretty soon, you’ll have more energy, so make sure to talk with your OB about a safe exercise plan for the rest of your pregnancy. Regular workouts may help manage weight gain, make your heart and lungs strong, decrease pain and potentially reduce risk of issues such as gestational diabetes.

Key Takeaways at 13 Weeks Pregnant

Good news: You should hopefully start feeling more like yourself soon, as you enter your second trimester. The initial pregnancy exhaustion may fade and the nausea might too! The honeymoon phase of pregnancy is approaching, meaning you might get a burst of energy for a few weeks.
You might have a 13-week ultrasound or possible non-invasive prenatal testing (NIPT), which looks for chromosomal abnormalities. Baby’s sex might be detectable at this point too—but not guarantees.

The end of week 13 is the end of the first trimester! We’re not just talking about getting through those work meetings without falling asleep (or puking), we’re talking about how you’re now 1/3rd of the way through your pregnancy! At 13 weeks pregnant, you’ve grown a fetus that has vocal cords, teeth and even fingerprints (wow!), and you’ve probably kept this incredible news (mostly) secret while wishing you could shout it from the rooftops—or, at the very least, use it as an excuse for getting to work late.

Watch Week 13 Highlights

Baby at Week 13

That little cutie of yours is growing fast as you approach the second trimester. Here’s what you can expect.

How big is baby at 13 weeks?

At 13 weeks, baby is as big as a lemon. Your 13-week fetus is about 2.9 inches long and weighs about .81 ounces, and proportion-wise, their head is now about 1/3 the size of the body instead of 1/2.

13 weeks pregnant is how many months?

At 13 weeks pregnant, you're three months pregnant, although doctors track pregnancy by week, not month. This is the last week of the first trimester. (We can’t say it enough because it’s so great to be here!)

13 week ultrasound

A 13-week ultrasound could detect baby’s sex, but since it can be pretty tough to make out little boy or girl parts, your doctor will probably wait until the mid-pregnancy ultrasound (around 18 to 22 weeks), when it will be much more obvious, to look and see whether you’re having a girl or a boy.

If you’ve chosen to have prenatal cell-free DNA testing, also known as non-invasive prenatal testing (NIPT), to screen for chromosomal abnormalities, you’ll be able to find out the sex when you get your results. Hey, at 13 weeks, you may already know! Oh boy! (Or girl!)

Pregnancy Symptoms at Week 13

You might notice that around 13 weeks pregnant, your symptoms change a bit. You might actually be able to get through the day without nausea (if not now, soon) or feeling the need to nap. But you may be experiencing a few of these 13 weeks pregnant symptoms too:

Visible veins

You can see all those blue streaks and spider veins under your skin because you have increased blood flow.

Increase in energy

The second trimester is known as the least symptomatic and the most energetic. As you start to feel more like yourself and get that energy surge, you’re going to want to knock a bunch of to-dos off your list. Also, if you’ve found yourself too sick and tired to exercise lately, now’s the time to get back to a fitness routine. Exercise will only benefit you and baby and can even make labor easier. Worth it!

Increased sex drive

If you’re one of those lucky pregnant women who feels up for a roll in the hay at 13 weeks, enjoy! You may notice a bit of post-coital spotting during pregnancy at 13 weeks. A little spotting is normal simply because your cervix is more sensitive. But heavy bleeding (like a period) isn’t, so call your doctor if it’s more like a flow. Otherwise, you and your partner can use your increased sex drive to enjoy some together time before baby arrives!

Sorry, twin moms-to-be. If you’re 13 weeks pregnant with twins, you might still be experiencing some morning sickness and fatigue. That’s because twin moms can have more of the pregnancy hormone hCG in their systems. If your nausea and vomiting is super severe, definitely bring it up to your OB. If you’re able to hold down food and liquids but you’re still feeling ill, just wait it out a little longer.

What should I expect at 13 weeks pregnant?

At 13 weeks pregnant, you’re turning the corner and may even feel like a new woman after a first trimester of morning sickness, fatigue and other issues. You may experience 13 weeks pregnant symptoms, as well as some indigestion, achiness and tiredness that’s typical in the first trimester. Expect to feel a lot more at ease in the second trimester!

Your Pregnant Belly at 13 Weeks

Your uterus is now big enough that it’s growing up and out of your pelvis. That means you’re starting to actually look pregnant. Finally, right? Expect to look more and more pregnant from here on out, because carrying a 13-week fetus calls for a weight gain increase. OBs recommend you gain weight in the healthiest way possible—that means slowly and steadily throughout your pregnancy. Here are the weight gain guidelines outlined by the American College of Obstetricians and Gynecologists (ACOG):

If you’re underweight (BMI under 18.5):

Your recommended total pregnancy weight gain is 28 to 40 pounds.
In the second and third trimesters, aim to gain about a pound (1 to 1.3 pounds to be exact) per week.

If you’re normal weight (BMI of 18.5 to 24.9):

Your recommended total pregnancy weight gain is 25 to 35 pounds.
In the second and third trimesters, aim to gain about a pound or a little less (0.8 to 1 pound to be exact) per week.

If you’re overweight (BMI of 25 to 29.9):

Your recommended total pregnancy weight gain is 15 to 25 pounds.
In the second and third trimesters, aim to gain a little over a half pound (0.5 to 0.7 pounds to be exact) per week.

If you’re obese (BMI of 30 and above):

Your recommended total pregnancy weight gain is 11 to 20 pounds.
In the second and third trimesters, aim to gain about a half pound (0.4 to 0.6 pounds to be exact) per week.

If you’re 13 weeks pregnant with twins:

Your recommended total pregnancy weight gain is 37 to 54 pounds.
In the first half of your pregnancy, aim to gain about a pound per week. In the second half, aim to gain a little over a pound per week.

Of course, you don’t want to stress yourself out about these numbers. What’s important is that you’re eating a healthy diet full of a variety of different foods, eating about 300 extra (nutritious) calories per day more than you did pre-pregnancy and getting plenty of exercise.

How does your belly feel at 13 weeks pregnant?

You’re probably feeling great in terms of nausea and morning sickness! However, to make room for your fast-growing 13-week fetus, your uterus is moving upward and outward. This expansion can cause stretch marks and itchy belly skin. Don’t forget to moisturize and eat well to keep skin soft and supple!

Can you feel the baby at 13 weeks?

Possibly! It’s different for everyone, but some women (particularly those who have been pregnant before) may start to feel those telltale movements when baby’s at 13 weeks. If you haven’t felt the first flutters yet, don’t worry—it can take up to 25 weeks along to feel what’s called “the quickening.”

It's debatable how much one's calorie needs actually increase during pregnancy, because the data shows that it varies widely between women (though usually in the ballpark of 300 to 500 calories extra). One researcher suggests that the adage of ‘eating for two’ be replaced with ‘eating for 1.1’ to better reflect the moderate increase in calories per day. Focus on nutrient-dense foods, so every bite is as packed with nutrition as possible.

Tips for 13 Weeks Pregnant Symptoms

Know the signs of a UTI

Left untreated, a urinary tract infection can potentially travel to the kidneys and pose a health risk for Mom and baby. If you need to use the bathroom more often than usual, feel burning during urination or it looks or smells unusual, visit your doctor, who can test for bacteria and prescribe antibiotics.

Strengthen your pelvic floor

When you’re carrying a baby at 13 weeks, your body needs all the support it can get. Your pelvic floor can weaken from pregnancy and labor, but you can do Kegel exercises to strengthen the area. They don't take a lot of time or effort, and a regular routine during pregnancy can pay off with less urinary leakage after you give birth and enhanced sexual sensations. Sounds good!

Find some together time

You and your partner may be hot and heavy between the sheets right now, but have some fun outside the bedroom too, so you can spend quality time with each other before baby makes three.

Eat a good breakfast

No more morning sickness? Breakfast is served! It’s the perfect time to get calcium, protein and the powerful nutrients that come from produce and whole grains. A healthy morning meal can also help you set the tone for nutritious eating for the rest of the day.

Weight during pregnancy.

What increase is considered optimal?

Why is excessive weight gain during pregnancy particularly harmful? What should be the calorie content of the diet? How to build your diet so that you can eat varied (and tasty), but at the same time not gain too much? Let's figure it out.

What makes up weight gain during pregnancy?

An increase in the subcutaneous fat layer during pregnancy is a normal and natural process.

While the baby is growing inside you, he needs energy and external protection. But during pregnancy, weight increases not only and not so much due to the adipose tissue of the mother: there is more fluid in the body, the uterus grows, the fetus and placenta develop, and the breasts increase in preparation for the feeding process.

Interestingly, weight loss during the period of toxicosis can later provoke its increase: the body will try to regain what was lost.

Expectant mothers especially actively gain weight in the second trimester and the beginning of the third, but closer to childbirth, a pregnant woman can even lose 1-2 kilograms.

As long as the weight increases more or less evenly and does not go beyond the upper limit of the norm, there is nothing to worry about. But if your weight is rapidly going up, you should be wary.

How to correctly calculate the weight, and what increase is considered optimal?

In Russian obstetric practice, it is generally accepted that the total gain should not exceed 12 kg. for the entire pregnancy. Of these 12 kg. 5-6 accounts for the fetus, placenta, amniotic fluid, another 1.5-2 - for an increase in the uterus and mammary glands, and only 3-3.5 - for the fat mass of a woman.

But this is a general indicator, a kind of "average temperature in the hospital." The optimal increase is calculated individually and depends on the initial weight of the pregnant woman, her age, the number of fetuses and the size of the child (children), physical activity.

WHO recommends that optimal weight gain be calculated based on Body Mass Index (BMI).

It is determined by the formula: body weight (kg) / height squared (m).

BMI	Recommended weight gain
19.8-26 (normal body weight)	12.5-15 kg
26.1-29 (overweight)	11.5 - 14 kg
over 29 (obese)	7-9 kg

How to calculate the optimal weight gain?

To do this, use the following chart:

Calculate your BMI: divide your initial weight in kg. for height in meters squared.

For example, your "pre-pregnancy" weight was 60 kg with a height of 170 cm.

BMI = 60: (170 x 170) = 20.76.

A BMI of less than 18.5 indicates underweight. Indicators from 18.5 to 25 are within the norm, from 25 to 30 are above the norm, and a figure greater than 30 indicates obesity.
Now that you know your BMI, find the optimal weekly increase in the table and compare it with yours.

Week of pregnancy	Underweight before pregnancy (BMI less than 18.5)	Normal pre-pregnancy weight (BMI 18.5 to 24.9)	Overweight before pregnancy (BMI over 30)
4	0-0.9 kg	0-0.7 kg	0-0.5 kg
6	0-1.4 kg	0-1 kg	0-0.6 kg
8	0-1.6 kg	0-1.2 kg	0-0.7 kg
10	0-1.8 kg	0-1.3 kg	0-0.8 kg
12	0-2 kg	0-1.5 kg	0-1 kg
14	0.5-2.7 kg	0.5-2 kg	0.5-1.2 kg
16	up to 3.6 kg	up to 3 kg	up to 1.4 kg
18	up to 4.6 kg	up to 4 kg	up to 2. 3 kg
20	up to 6 kg	up to 5.9 kg	up to 2.9 kg
22	up to 7.2 kg	up to 7 kg	up to 3.4 kg
24	up to 8.6 kg	up to 8.5 kg	up to 3.9 kg
26	up to 10 kg	up to 10 kg	up to 5 kg
28	up to 13 kg	up to 11 kg	up to 5.4 kg
30	up to 14 kg	up to 12 kg	up to 5.9 kg
32	up to 15 kg	up to 13 kg	up to 6.4 kg
34	up to 16 kg	up to 14 kg	up to 7.3 kg
36	up to 17 kg	up to 15 kg	up to 7.9 kg
38	up to 18 kg	up to 16 kg	up to 8.6 kg
40	up to 18 kg	up to 16 kg	up to 9. 1 kg

Recently, doctors are increasingly talking about an individual approach and urge not to panic if the increase is slightly beyond the normal range. When assessing the state of health of a pregnant woman, the doctor focuses not only on weight, but also takes into account the results of tests and examinations and other important indicators.

Why is excessive weight gain dangerous?

Gaining extra pounds can lead to gestational diabetes, hypertension, preeclampsia, or cause a caesarean section.

In addition, excessive weight gain during pregnancy may increase the risk of obesity and associated cardiovascular disease.

What can I do to keep my weight within normal limits during pregnancy?

First of all, consult a nutritionist. If there is no such doctor in the antenatal clinic, it makes sense to contact a specialist on a commercial basis. He will develop an individual diet, which will contain all the useful elements, and will offer to keep a food diary. It will also tell you how to eat right and weigh yourself.
To prevent excessive weight gain during pregnancy, it is enough to follow simple rules of a healthy diet:

Eat often and in small portions;
Always keep a “healthy snack” on hand: fresh apple wedges, unsweetened crackers, dried fruit, or sugar-free yogurt;
Refuse soda, chips, sausages and sausages;
Minimize sweets;
Avoid fast food;
Limit the use of condiments, especially salt, which retains water in the body;
Choose steamed dishes;
Eat more fiber-rich foods such as whole grain bread, bran, vegetables;

The diet of a pregnant woman should be varied. Include grains, vegetables, fruits, dairy products, meat and fish, legumes, or nuts.

It must be remembered that expectant mothers should never starve and adhere to extreme diets.

How many calories per day do you need during pregnancy?

It is difficult to calculate the energy value per day on your own, and then strictly adhere to a certain number of calories, and it is not necessary, unless it is recommended by a nutritionist or endocrinologist. On average, you can aim for 2000-2500 calories per day, but it is important to understand that the need for calories depends on many factors: age, initial weight, health status and level of physical activity.

When should I be on the alert?

Strictly speaking, it is better for a pregnant woman not to worry and entrust her condition to a doctor who will control the development of pregnancy, analyzes and monitor weight. It is important to take tests to determine the level of fasting blood glucose once a trimester. The appearance of glucosuria, an increase in fasting blood glucose (more than 5.5 mmol / l) or an hour after a meal (more than 7.7 mmol / l) indicate the possible development of "diabetes in pregnancy", in connection with which the doctor will prescribe appropriate treatment . In addition, a sharp increase in body weight can cause preeclampsia.

These and other diseases can be dangerous, which is why you need to carefully monitor the body weight during the gestation period, but remember that pregnancy is not the time for strict diets.

Weekly pregnancy weight calculator

The weight of the expectant mother is very important for the development of the fetus. It is desirable to have a normal body weight before pregnancy. Lack of weight is a serious risk factor, as a result of which a child may be born too small.

Being overweight increases the likelihood of having an oversized baby. In such situations, only a timely caesarean section made by obstetricians can help.

Weight in the first trimester

In addition to body weight before conception, weight during pregnancy by weeks and its constant control play an important role. In the first couple of months, it increases slowly, the baby and mother only adapt to each other. During this period, there are frequent cases of toxicosis, which additionally reduces weight. During the first trimester of pregnancy, a woman gains about 1.5 kg.

Weight in the second half of pregnancy

Intensive weight gain occurs in the second half of the term. Most women gain only 40% in the first 4 months, and the remaining 60% in the second half. However, it also happens the other way around - in some women, weight during pregnancy is gained week by week faster in the first months, there is no pathology in this.

The increase is distributed as follows:

Fat	28%
Water	13%
Fruit	27%
Blood	10%
Uterus	8%
Amniotic fluid	6%
Placenta	5%
Breast	3%

Permissible weight gain

If we take the allowable value of weight gain in women, then it is 350 g per week (50 g per day), with a maximum of 500 g per week. Using the weight calculator during pregnancy, you can find out what it should be at different times. To exceed this norm, it is desirable to lead an active life and monitor nutrition. Although an extra increase is undesirable, in no case should you exhaust yourself with hunger strikes. And there is nothing good in the abuse of flour products in an attempt to get to the norm either. You need to eat something that will benefit not only you, but also the child.

To obtain an accurate calculation, enter the following digital data into the pregnancy weight calculator:

initial weight;
growth;
approximate gestational age in weeks.

What causes the difference in weight in different women at the same time?

The difference can be due to several reasons. One of them is age; with increasing age, the tendency to be overweight also increases. More weight is gained by women with a lack of mass before pregnancy and who have undergone early toxicosis. The body thereby tries to compensate for the losses.

An important factor is the peculiarity of the constitution, the difference with the readings of the weight calculator during pregnancy by weeks may be due to a tendency to thinness or fullness. It also depends on the size of the baby: the larger it is, the larger the placenta will be. Sometimes a sharp increase in the appetite of the expectant mother leads to intensive weight gain, it is quite difficult to deal with it.
