BabyCenter's Due Date Calculator

Use our pregnancy due date calculator by plugging in either the date of your last menstrual cycle or the date you know you conceived. The calculator will do the rest.

How is my due date calculated?

There are several ways your due date is determined. If you happen to know the day you conceived, you can count 38 weeks from that day to find your due date. (Human gestation takes about 38 weeks.)

But very few expectant moms know exactly when they conceived. Even if you only had sex once during your fertile period, you wouldn't conceive on that day unless you happen to be ovulating. Sperm can live for up to five days inside your fallopian tubes. So, it could be up to five days after you have sex that you release an egg (ovulate) and it gets fertilized by a waiting sperm. That's the day you conceive.

So, without knowing the day of conception, how does anyone determine a due date?

First day of your last period

The most common way to calculate your pregnancy due date is by counting 40 weeks from the first day of your last menstrual period (LMP). And that's how most healthcare providers do it.

If your menstrual cycle length is the average length (28-day cycle), your menstrual cycle probably started about two weeks before you conceived. This explains why pregnancies are said to last 40 weeks instead of 38 weeks.

This method doesn't take into account how long your menstrual cycle actually is or when you think you might have conceived. But generally speaking, women typically ovulate about two weeks after their menstrual cycle starts. And women are more likely to know when their last period started than the day they ovulated.

Conception date

If you do happen to know precisely when you conceived – say, if you were using an ovulation predictor kit or tracking your ovulation symptoms – you can calculate your pregnancy due date based on your conception date. Just choose that calculation method from the pulldown above and put in your date.

Note: Again, you don't necessarily conceive on the day you have sex.

IVF transfer date

If you conceived through IVF, you can calculate your due date using your IVF transfer date. If you had a Day 5 embryo transfer, count 261 days from your transfer date. If you had a Day 3 embryo transfer, count 263 days.

Can my due date change?

Your healthcare provider might revise your due date if your baby is measured during a first trimester ultrasound scan and found to be much bigger or smaller than expected for gestational age. This is more likely to happen if you have an irregular menstrual cycle length that makes it hard to pinpoint the date of conception.

Your healthcare provider will measure your baby during that ultrasound exam to figure out how far along your baby is and then provide you with a new due date.

What if I already know my due date?

If you already know your due date, you can use this calculator to see your pregnancy timeline. It will tell you when you'll hit various milestones, and when you may be due for prenatal tests and prenatal visits. You'll also find what your baby's sign and birthstone will probably be and which famous people were born on your due date.

How likely am I to give birth on my due date?

Of course, a due date calculation is always approximate, whether it's from our tool or from your doctor or midwife. Only 1 in 20 women delivers on her due date. You're just as likely to go into labor any day during the two weeks before or after.

How soon can I take a pregnancy test?

With all this talk about pregnancy due dates, you may be wondering when you can take a pregnancy test. To ensure you get the most accurate reading, it's best to wait a few days after your missed period to take a pregnancy test.

At-home urine tests measure the amount of hCG (human chorionic gonadotropin) present in your body. If you take a pregnancy test before you miss your period, you may not get an accurate result, despite what some tests advertise.

If you're getting a blood test in your provider's office, you may get results sooner. These tests also measure the amount of hCG in your bloodstream, but they're more sensitive than at-home urine tests. Blood tests may be able to detect pregnancy six to eight days after ovulation.

Prosecutor explains

Is it possible to change the date and place of birth of an adopted child?

Text

Yes, indeed, the legislator regulates such an opportunity to ensure the secrecy of adoption.

In accordance with the provisions of Art. 135 of the Family Code of the Russian Federation, at the request of the adopter, the date of birth of an adopted child can be changed, but not more than three months, as well as the place of his birth.

Changing the date of birth of an adopted child is possible only when adopting a child under the age of one year. For reasons recognized by the court as valid, a change in the date of birth of an adopted child may be permitted when adopting a child who has reached the age of one year or older.

In addition, at the request of the adoptive parents, the court may decide to record the adoptive parents in the birth register as the child's parents.

These changes are indicated by the court in the adoption decision.

how to determine the nature of the child by date of birth?

We tell you what your baby's date of birth means and how to find an approach to it from the point of view of numerology.

Your baby is a growing personality with an individual character, talents and his own vision of what is happening. Sometimes in the process of education, parents do not take into account the characteristics of their children and use template techniques. Why is this happening? They just do not know how to identify the individual characteristics of the baby. But the main task of parents is to help in the full development of the child so that he can become a harmonious personality. Understanding these features sometimes requires a little desire and effort. And numerology will help you with this!

By simply adding the numbers of the date of birth, you can find out the number of your child's fate, and, after reading the explanations for each figure, identify important qualities and promising directions for development. For example, the date of birth is September 28, 2014. The number of fate is calculated as follows: 2 + 8 + 0 + 9 + 2 + 0 + 1 + 4 = 26 = 2 + 6 = 8. After that, it remains only to find out the value of this number.

Number 1. A child with the number "1" is the undisputed leader. He is prone to active actions, requires constant attention and dreams of independence from others. The child cannot be limited by any prohibitions and frameworks. Do not extinguish the makings of leadership, as they will be useful to him in adulthood. Direct energy in the right direction, give good advice and provide support.

Number 2. To characterize such a child, one word is enough - "charming". Despite his increased sociability, he is quiet and shy. A child with such a fate number is not in conflict, never offends peers and spends a lot of energy trying to please others. Support him, instill in him self-confidence and give your love.

Number 3. Such a child loves to attract attention and will do everything to get the attention of others. He is not capricious, sociable and often becomes a favorite of teachers at school. Parents should teach such a child to concentrate on a single task. By the way, such children are often touchy, so try to choose the right words - this will help to avoid misunderstandings.

Number 4. The child is so organized and methodical that some parents will have to learn from him. He loves to be left to himself, hates invasions of personal territory. At the same time, the child is trusting and generous, and, despite independence, needs the love of his parents no less than others.

Number 5. A child with a destiny number of 5 is curious and restless, does not like to be controlled by others and loves to argue on any occasion. You literally have to hide everything from him, because otherwise he can get hurt or ruin something. Despite the outward unkindness, he loves his parents very much.

Number 6. Such a child should not be left alone, he should always be in a friendly company. Despite the fact that he is capricious, he does not lack charm and friendliness. Try to balance the increased emotionality of the baby and remember that he is offended by any criticism. Maintain his self-confidence and show more tender feelings.

Number 7. This is perhaps the most difficult type of character from the entire numerological cycle. He has an opinion on any occasion, and it will not be easy to convince him. This is a very calm and sensitive baby who will bring a lot of joy to his parents. The main advantage is intelligence. Develop and support them as much as possible.

Number 8. A charming child who actively uses personal charm to solve all his problems. Convince your child that you love him. They are real jealous and possessive. Become an authority in his eyes, otherwise he will do it for you. Try to explain to the child what is good and what is bad, try to give comments in the correct form.

Number 9. The child has many talents and a great imagination. Despite the capriciousness, he will not give you trouble.
