21 week baby movements
Your Baby's Movements During Pregnancy – Health Information Library
Overview
During your pregnancy, you'll feel your baby move. For example, your baby may kick, hiccup, roll, turn, and twist. These movements are common and expected. As your baby grows, these movements will get stronger.
But sometimes you might feel a movement that surprises you. You may wonder what it means. Most pregnant women don't have any serious problems. But it's a good idea to learn about the different kinds of movements. They include:
- Fluttering, butterflies, or bubbles.
-
You'll probably start to feel your baby move sometime between 18 and 22 weeks. At first, these small movements feel like fluttering or "butterflies. " Some women say that they feel like gas bubbles. These first flutters are sometimes called "quickening."
- Hiccups.
-
Around 21 to 24 weeks, you may start to feel some jerky movements inside your belly. You might even see them on the outside. Repeated jerky movements usually mean that your baby has the hiccups.
Hiccups are perfectly normal. They can last from a minute to an hour. You may feel your baby have hiccups now and then throughout the rest of your pregnancy.
- Kicks, twists, and turns.
-
As your pregnancy goes on, you may feel some changes in your baby's movement. Around 25 to 28 weeks, your baby may start to kick and stretch. And you may notice that your baby does less turning and twisting and more squirming or jerking. Around 30 to 32 weeks, your baby turns less and kicks and jabs more.
At about 28 weeks, you may feel your baby move from head-down to feet-down, or even sideways.
When and how often babies move
After 18 to 20 weeks, you may notice that your baby moves more at certain times of day. For example, when you are active, you may feel less movement than when you're resting quietly. Believe it or not, babies find the activity and noise of daytime hours to be soothing. So they often sleep during the day and are awake at night.
Starting at about 30 to 32 weeks, you should feel your baby move several times a day. Babies usually sleep 20 to 45 minutes at a time, and then are more active at certain times of day.
By 40 weeks, your baby has grown larger and doesn't have much room to move around. You will probably notice less "big" movement than before.
Call your doctor or midwife right away or seek immediate medical care if you notice that your baby has stopped moving or is moving much less than normal.

Baby at Week 21
Wondering what’s going on with your 21-week fetus? As baby's digestive system preps for the outside world, they’re manufacturing meconium, the tarry black substance you'll find in the first dirty diaper.
Bet you hadn’t even thought about future grandchildren yet, but the reproductive system is developing too. If it's a girl, she's already got a lifetime supply of eggs in her womb—about six million of them! Having a boy? His testes are still located in his abdomen but will drop in the coming weeks once the scrotum finishes developing.
How big is baby at 21 weeks?
At 21 weeks pregnant, baby is as big as a head of endive. At 10.5 inches and about 12.7 ounces, baby is big enough now that you've probably been feeling their fetal movements more and more lately. Keep in mind that at 21 weeks, baby size is now measured in full body length, rather than crown to rump, so you can get a real idea of how big your baby is at 21 weeks pregnant!
What is baby doing at 21 weeks in the womb?
Now, at 21 weeks, fetal movement is noticeable—and baby has reflexes too! If you gently press your palm on your belly, you might feel a little push back. So cool! Baby at 21 weeks is practicing coordinated movements and enjoying the room they currently have in your uterus, which means they also need 12 to 14 hours of sleep every day. Baby at 21 weeks is also practicing swallowing amniotic fluid (don’t worry, it’s just practice—baby still gets everything they need through the placenta) and growing taste buds as well as head and body hair.
21 weeks pregnant is how many months?
Twenty-one weeks pregnant is five months pregnant, although doctors track pregnancy by week, not month. Since pregnancy is 40 weeks long, you’re now a majority of the way through your pregnancy!
21 week ultrasound
You’ll get a glimpse of that cute little 21-week fetus if you have your mid-pregnancy ultrasound this week. This 21 weeks ultrasound will amaze you! Not only will you get to see baby on the screen, you’ll also get to see some awesome details like the brain hemispheres and chambers of the heart. Let your technician know whether or not you want to know baby’s sex.
Finding out whether it’s a boy or a girl is a pretty exciting moment! But you can also save it for later if you want. Some parents-to-be wait until baby is born to know the sex. Or you could ask the technician to write it down and put it in an envelope so you can take it home. Then, you could plan a gender reveal party, where you can find out the surprise while surrounded by your family and friends. Fun!
At 21 weeks pregnant, pictures of baby are bound to be adorable! Ask for lots of printouts of the pictures, because if you have an uncomplicated pregnancy, this may be the last medical ultrasound you’ll get during pregnancy. Now go show off those photos of your cutie! And keep brainstorming those names!

Pregnancy Symptoms at Week 21
Common 21 weeks pregnant symptoms are kind of like a sneak preview of the third trimester. Here’s what you might be feeling at week 21 of pregnancy:
Heartburn and/or indigestion
Avoid spicy and greasy foods and other triggers to control your heartburn and indigestion. If the source of your discomfort is a mystery, keeping a food diary could help you figure it out.
Braxton Hicks contractions
Your uterus might occasionally feel tight as it practices for labor. Braxton Hicks at 21 weeks are totally normal as long as the contractions go away when you switch positions. Let your doctor know about any pain or contractions that don’t stop.
Leaky boobs
Your milk ducts will be fully developed by the end of this trimester—just in case of an early arrival—so you may experience some leaking from your breasts.
Dry, itchy skin
Your skin is stretching over your growing bump, making it drier and more irritated by the day. Lather up with a pregnancy-safe body oil or lotion to help your skin stay moisturized and hopefully less itchy. Also, if you develop a rash, let your doctor know right away, since that could be a sign of an annoying pregnancy condition called PUPPP.
Stretch marks
Your skin gets pulled thinner as baby grows, causing tiny tears beneath the surface of your skin. Stretch marks are more common for some women simply because of family history or because of sudden weight gain. They are also more common in women who are 21 weeks pregnant with twins. There’s no way to truly get rid of stretch marks, but they should fade significantly after birth.
When should I worry about Braxton Hicks at 21 weeks?
You shouldn’t worry at all unless the contractions don’t stop after a couple minutes, get stronger and closer together or there’s fluid or bleeding from the vagina. In those cases, call your doctor. Otherwise, Braxton Hicks contractions are prepping your uterus for all that hard work contracting during labor. Braxton Hicks at 21 weeks are normal but usually just periodic. They rarely last more than two minutes and are often brought on by sex and orgasm, a full bladder, dehydration or a big kick from baby.
Your Pregnant Belly at 21 Weeks
This week, you may look in the mirror at your 21 week baby bump and wonder, “Where did I go?!” By the time you reach 21 weeks pregnant, you may have gained around 13 to 14 pounds, and around 21 pounds if you’re 21 weeks pregnant with twins.
Your newfound curves might have you feeling super sexy and confident—after all, you’re the center of attention wherever you go! But the extra weight also might have you feeling self-conscious. Remind yourself, you’re supposed to be gaining this weight and do your best to embrace those curves! It’s good for you and for baby.
In fact, all the weight you gain during pregnancy isn’t just padding for baby—it all serves a really important purpose. Here’s a logical way to think of it: Of the approximately 30 pounds you’ll gain throughout your pregnancy, there’s a whole lot more than fat. Here’s what makes up that weight:
- An average full-term baby = 7.5 pounds
- Placenta = 1.5 pounds
- Uterus = 2 pounds
- Amniotic fluid = 2 pounds
- Maternal stores of fat, protein, and other nutrients (needed for breastfeeding!) = 7 pounds
- Breast tissue (also for breastfeeding, of course) = 2 pounds
- Increased fluid volume = 4 pounds
- Increased blood volume = 4 pounds
See? All those pounds are doing a lot of good, keeping baby alive and healthy—and storing up good stuff to nourish them after birth. Anytime you’re feeling a little meh about your body, think of all the amazing things it’s doing!
What to expect at 21 weeks pregnant with twins
If you’re 21 weeks pregnant with twins, your belly is getting tight, itchy and dry, and you may have already developed some stretch marks. Keep rubbing that 21 week baby bump with plenty of lotion to ease the itchiness. Heartburn is probably a close personal friend at this point too, so watch what you eat to make sure you don’t make it worse, and keep meals smaller and more frequent. If that doesn’t do it, talk to your doctor about a pregnancy-friendly antacid.
Remember that each pregnancy is different. Don't compare yourself to other pregnant women or try to compare your experience with previous pregnancies. Just relax and enjoy this special time!

Tips for 21 Weeks Pregnant
You’re moving and grooving through this pregnancy. The next 19 weeks or so are going to fly—or crawl (depending). In the meantime, here’s what you should do right now.
Drink your water
Water can help with 21 weeks pregnant symptoms. As counterintuitive as it may seem, staying hydrated keeps your body from retaining water; it also helps calm those Braxton Hicks contractions and is your best bet for fending off UTIs.
Keep moving
Exercise may sound like a chore right now, but it’ll help with swelling and circulation. Try prenatal yoga, an easy walk or swimming if that belly is feeling extra heavy these days.
Sign up for classes
If you’re interested in taking childbirth classes, breastfeeding classes or infant care classes, now is the time to sign up if you haven’t yet. Classes often fill up early, so get them on the books before your final month.

21-24 weeks of pregnancy
21st week of pregnancy
Development of the baby
At 21 weeks the baby is about 25 cm tall and the fetus weighs 300-400 g. lack of subcutaneous fat, the body is still very thin, and the head seems unnaturally large. At this time, the formation of eyelashes and eyebrows takes place, the baby learns to blink, and his skin gradually acquires a flesh color, thickens, constrictions appear on it.
At the 21st week, the muscles and skeleton of the fetus are actively developing. The child constantly moves, carefully bends and unbends the limbs, due to its small size it can do somersaults, turns, change the position of its body several times a day, lie transversely in the uterus, turn up or down with its head.
At this stage, the baby hears well, not only distinguishes sharp sounds, but reacts to music, so the expectant mother can listen to classics or favorite songs, contribute to the development of the child. The development of the digestive system continues, taste buds are formed. The fetus is able to distinguish the taste of amniotic fluid.
Pregnant woman
Pregnant woman at 21 weeks feels normal. The expectant mother clearly feels the movements of the fetus; very often, the periods of sleep and activity of the child and the woman do not coincide, so pregnant women do not get enough sleep during this period, they wake up at night due to the intensive movements of the baby. Painful sensations at this time are quite rare, since the child does not have sufficient physical strength, and his movements do not differ in intensity.
A pregnant woman may put on weight as the baby grows, its muscle and fat mass increases. Expectant mothers eat with pleasure. Their appetite increases significantly, morning sickness and general malaise disappear.
At this time, the baby's skeleton is formed, for the development of which calcium is needed. Pregnant women should monitor their health, take calcium supplements as prescribed by a doctor, since if it is lacking, problems with teeth are possible. Calcium is washed out of the tissues, the teeth begin to hurt and crumble. It is important not only to consume vitamins, but also to carefully balance the diet, add calcium-rich cottage cheese, sour cream and other dairy products to the daily menu. The consumption of fish, cereals and legumes, vegetables will help to fill the calcium deficiency.
22nd week of pregnancy
Development of the child
The body length of the fetus reaches 28-30 cm and its weight is approximately 500 g. The child more and more resembles a newborn, his head no longer looks so big, the length of the limbs increases. The kid no longer keeps his legs constantly bent, he periodically straightens them. Intensively increases the volume and mass of the child's brain.
The baby is in constant motion, he can move his fingers and toes, move his head to the right and left. The child knows how to suck his thumb, he tilts his head forward and accurately puts his finger in his mouth. Such actions indicate an increase in sensitivity and development of the vestibular apparatus, improved coordination; the child already feels the position of his own body in space.
The baby's brain at this time contains a complete set of neurons, the number of which does not change throughout a person's life. With age, only the re-formation of connections between cells and the improvement of the work of the human brain takes place.
Pregnant woman
At 22 weeks, the uterus of a pregnant woman is located 2 cm above the navel. The abdomen is not yet very large, but the internal organs are already beginning to shrink due to the accelerated growth of the uterus. A woman may experience some discomfort, pain between the lower ribs. In order not to suffer from pain, you must constantly monitor your posture, choose a comfortable chair with a solid back for work. Special exercises, periodic changes in body position, turns and inclinations will help to solve the problem. It is necessary to avoid sedentary work, take short breaks and fully relax.
The bottom of the uterus can press on the stomach, so a common problem at this time is a feeling of heaviness after eating and heartburn. The position of the stomach in pregnant women changes to a more horizontal one, the muscle relaxes, which closes the transition from the esophagus to the stomach, as a result of which the contents of the stomach fall back into the esophagus, irritate it, the woman feels a burning sensation and an unpleasant aftertaste. The reason for such changes is not only the pressure of the uterus on the stomach, but also a change in the hormonal background of a woman, an increase in the content of progesterone in the body. To get rid of heartburn, you need to chew food thoroughly, eat often, but in small portions. Do not eat before going to bed, as the food will not have time to be digested. If the symptoms worsen, it is necessary to consult a doctor who will prescribe the necessary medications and help the expectant mother balance her diet.
23rd week of pregnancy
Child development
The 23rd week is an intensive formation of the respiratory system. The fetus begins to gradually make respiratory movements. If earlier the respiratory movements were periodic, now their duration can reach up to 40 minutes. In a minute, the child takes up to 50-60 breaths. The development of the respiratory system does not stop at this time, a kind of breathing exercises continue until childbirth, the baby improves skills and prepares to breathe air.
When breathing in the womb, the baby swallows a small amount of amniotic fluid and then pushes it out. In this case, the epithelium is washed. When amniotic fluid is swallowed, part of it is absorbed by the blood vessels, and the original feces, that is, meconium, are formed from the remnants.
If the baby is very active and swallows water very intensively, diaphragm irritation and contractions, also called "fetal hiccups", may occur. These rhythmic movements are not abnormal; such hiccups pass in a few minutes, does not pose a threat to the expectant mother and child. If the contractions do not stop within a few hours, you should go to the hospital, as a more serious problem, including hypoxia, can be the cause of hiccups.
The 23rd week is an important stage in the intrauterine development of a person. It is at this time that the formation and improvement of the main components of the circulatory and immune systems, including the liver, lymph nodes, spleen and bone marrow, continue. At this time, the thymus gland (or thymus) develops, which plays an important role in the functioning of the human endocrine system. It is in the thymus that lymphocytes mature. After a kind of "training" in the thymus, the cells enter the bloodstream and can resist infection, neutralize foreign cells in the body.
During pregnancy, the fetal immune system goes through several stages of formation and cannot provide full protection against diseases. The baby is protected by maternal antibodies, while its own immune system learns to recognize potential threats, remember bacteria and viruses, and defend itself against their harmful effects.
Pregnant woman
At 23 weeks' gestation, the uterus rises even higher and is located at a height of 4 cm from the woman's navel. The volume of the uterus increases significantly not only due to the growth of the child, but also due to an increase in the mass and volume of amniotic fluid and the placenta. At this time, the weight gain of a pregnant woman of 5-7 kg is optimal. The expectant mother should carefully monitor the daily diet, do not overeat, since excessive weight gain can pose a threat not only to her health, but also to the baby.
Intensive growth of the uterus causes a shift in the center of gravity. A woman becomes awkward, may feel discomfort in the joints and pain in the spine while walking or sitting for a long time. At this time, the doctor may recommend that a pregnant woman wear special supportive underwear made from natural materials or a bandage.
24th week of pregnancy
Child development
At 24 weeks of gestation, the baby continues to grow rapidly, it weighs already 600 g, and its height is approximately 33 cm. The fetus occupies the entire uterine cavity, so its movements become less impulsive, but more distinct; sharp movements are replaced by smaller ones. The baby can still radically change the position of his body, but prefers to sort out the umbilical cord, play with it, bend and unbend the arms and legs. The amount of muscle mass, namely the muscle fibers of the child, increases sharply. At this time, this indicator reaches its maximum. At later stages of pregnancy, the muscle mass of the fetus increases due to an increase in the volume of each muscle fiber.
This week the child's senses are being improved. He knows how to distinguish tastes, hears perfectly and orients himself in space, the baby's skin has a high sensitivity. The fetal brain continues to develop, connections with the senses are formed, so the child's behavior is characterized by a high degree of complexity. Studies have shown that the child reacts to external stimuli: if a bright light hits his mother's stomach, he turns his head away, closes his eyes or covers his face with his hands. A woman should be calm and peaceful, because her fear, excitement is transmitted to the child, he begins to move intensively or freezes abruptly. The baby may react to harsh sounds, noise, or other stimuli.
Pregnant woman
The weight of the pregnant woman continues to increase, the increase this week is about 500 g. The belly grows, the uterus not only increases in size, but also stretches. A woman may notice pain in the abdomen, but they do not differ in intensity and do not last long.
Rapid weight gain can cause edema. The growing uterus compresses large veins, which, in turn, significantly complicates the outflow of lymph; a woman's ankles and feet, hands swell, in the evening the problem worsens. A pregnant woman should fully rest, lie more, while raising her legs with a roller or placing an additional pillow in order to improve the outflow of venous blood and eliminate the risk of varicose veins. It is important to purchase comfortable shoes, abandon the "boats" on the stiletto heels and provide the feet with the necessary comfort. Wearing compression tights and stockings will help to significantly reduce the risk of developing varicose veins and the appearance of edema. When choosing the degree of compression and models, it is necessary to take into account the opinion of a phlebologist or gynecologist.

4 min. for reading Feb. 17, 2022
In order for mothers to be calm and balanced, they need to know what their fetus is going through during this period and what to expect from their body.
How does the baby feel at 21 weeks pregnant?
The pregnancy calendar indicates that at this time all the indicators of the child are very different from those that were observed a few weeks ago. The fetus has grown, and its body has become stronger. His movements became clear and purposeful. Now mom will not miss his next push, which is felt more and more every week. The baby is more comfortable than ever - there is enough space in the uterus and he can move freely. At the 21st week of pregnancy, it often happens that the biorhythm of mother and baby does not match, and he begins to actively behave in the evening, preventing the parent from sleeping. In this trimester, he already hears sounds well, so calm him down by telling a story or singing a lullaby. Light strokes on the stomach also help.
The activity of the child now is the opportunity to assess his condition and the comfort of being in the uterus. If the movements are frequent or very few, this may indicate a lack of oxygen. At 21 weeks, the norm is when the fetus performs 200 movements in 24 hours. However, most of them cannot be felt. During the day, mom manages to catch about 15 movements. The lack of oxygen is easily eliminated with frequent air walks, light exercise for moms and breathing exercises.
The size of the child has already changed. In length at this time, it reaches - 26.7 centimeters, while its weight is up to 360 grams. But this is not the limit. Its size will still increase, because the internal organs are still being improved. First of all, this is the digestive system - it is preparing for full-fledged, independent work. The baby swallows amniotic fluid all the time so that they pass through the intestines. Thus, they are excreted through the rectum. It already has enzymes and hydrochloric acid in the digestive system in small amounts. The taste of the baby's first foods depends on what the mother eats, what drinks she drinks and whether she has bad habits. Therefore, it is important to lead a healthy lifestyle and eat healthy food.
How does the expectant mother feel at 21 weeks pregnant?
A woman's feelings during this period change - she constantly wants to eat, as the fetus becomes overgrown with fat and needs additional calories. Eat in moderation, but so as not to overeat and not feel hungry. Pregnancy at 21 weeks requires weight control, by this time you can recover by 4.5 - 6.5 kilograms.
Don't be surprised if you develop unusual food cravings and start liking strange food combinations - this is normal during this period. Now you can not raise your hands above your head, and if this still happened, do not keep them in this position for a long time. The body is already preparing for childbirth, so colostrum can be released at this time. If this happens - do not press, keep hygiene and wipe the chest. Also watch for vaginal discharge - thrush may aggravate. If you find any problems in yourself, contact your doctor immediately.
Ultrasound at 21 weeks of gestation
The development of the baby occurs in each week of the "interesting position". And if everything goes in positive dynamics for you, then at week 21 the doctor usually prescribes a second planned ultrasound of all trimesters. During the ultrasound examination, the doctor will tell you about the following points:
- whether the fetus develops normally;
- are there any threats;
- confirm or for the first time tell the sex of the baby;
- how active and strong the baby is.
Ultrasound at 21 weeks is a necessary procedure that will help assess the condition of the baby and its level of development. In addition, this is a good opportunity to exclude the presence of pathologies. During the examination, the doctor will carefully examine the baby's organs and compare their sizes with the dimensions of the fetus. Based on these data, conclusions are drawn about the nature of the course of pregnancy.
Nutrition tips for expectant mothers at 21 weeks of pregnancy
Remember that now the baby begins to recognize the taste of food, so it is worth eating only wholesome and healthy foods, as well as leading a healthy lifestyle. In addition, some foods may be harmful to his small body. It is important to consider the following:
- do not eat excessively salty foods;
- do not overeat and eat up at night;
- get rid of the habit of malnutrition;
- divide the daily ration into frequent but small portions;
- take more vitamins;
- no alcohol.
