Expecting a baby and want to know the arrival date? Use this pregnancy due date calculator to see the duedate by week, by month, and the pregnancy progress.
Due date calculator
Estimate your due date using your last menstrual period, conception date or date of your last ultrasound.
How to calculate my due date?
Typical pregnancies last for approximately 40 weeks or 280 days. So, the duedate is calculated based on this assumption. Based on what information is available to you, the pregnancy due date calculator can estimate the duedate. The most common way to calculate the pregnancy due date is to start from the first day of your last menstrual period (LMP). Add 40 weeks (280 days) to the first day of your last period. Another way to calculate pregnancy due date is to start with the first day of your last menstrual period (LMP). Add 7 days, and then count backward 3 months. For example, if your last period started on October 20, you would add 7 days to get October 27. Then subtract 3 months to get a due date of July 27.
Sometimes, your gynecologist may estimate the pregnancy due date based on the size of your uterus. In about 12 weeks of pregnancy, the uterus can be felt above the pelvis. After about 18 weeks, the distance between the pubic bone and the fundus is likely to be the same as the number of weeks since your last period. There are many approximate methods to measure the pregnancy week based on the uterus size.
An ultrasound can help estimate the pregnancy week if you don't know the exact first date of your menstrual period or when the ovulation has occurred. An ultrasound device sends sound waves to produce images on a screen, which allows viewing internal structures of the body and the fetus's growth and health.
These are some methods to predict the pregnancy due date. It is advised to consult the gynecologist to know more about the duedate and precautions during the pregnancy.
Can my due date change?
Yes. The actual duedate and pregnancy due date calculator estimations could differ. The exact due date of your baby depends on many factors. Your baby's growth, fundal height, level of alpha-fetoprotein (AFP) made by the baby, and so on. One more reason the due date can change in case if the estimates are a bit wrong. If you have irregular periods or your early ultrasound dating was off, the pregnancy duedate calculations may go a little wrong. Due date is just one indicator of your baby's arrival, but there are many tracks we need to keep and decide "the day." So, consult your gynecologist regularly to keep track of your and your baby's health.
Early pregnancy symptoms
There are so many reasons for you to think that you might be pregnant. Your period is missing, or it's late. You forgot to take pills. You forgot to use any contraception methods. You are feeling some changes in your body. A missed or delayed period is the most common first sign of pregnancy. There are many other early pregnancy symptoms like morning sickness, fatigue, light bleeding, breast changes, etc. Read this article to understand the early pregnancy symptoms and what they mean.
Pregnancy test
The question of "am I pregnant question?" can be triggered by many events and incidents. You have not used any contraception methods, or your periods are missing. Your body is behaving differently than usual. The complete pregnancy guide details all the tests, including home pregnancy tests, clinical urine pregnancy tests, pregnancy blood tests, and ultrasound/sonography scan tests. The pregnancy due date calculator needs the first day of your last period. So, if you don't know the exact date, the ultrasound pregnancy test may help estimate the pregnancy duedate and understand the baby's health.
Pregnancy vaccination
Pregnancy results in many immunity changes in a woman's body, becoming more susceptible to infectious diseases. These diseases can impact the pregnancy, fetus in the uterus, and newborn baby. Vaccine for pregnant women protects them and fetuses from infection by strengthening the body's immune systems to fight off severe infectious diseases. Pregnancy vaccination can guard the mother against vaccine-preventable infections and protect the newborn baby by transferring antibodies to the fetus. After knowing the arrival date estimated by the pregnancy due date calculator is essential to know what vaccinations you need to take till the duedate. This article details vaccinations like the Tdap vaccine, TT injection, others, benefits, and schedule.

The pregnancy due date calculator provides the estimated delivery date (EDD), the approximate date when you may go into labour. This is just an estimate, and your labour may start about two weeks before or after your calculated duedate. The actual due date may depend on one the number of pregnancies. Generally, the due date may be little earlier than the estimated due date for the second or later pregnancies.
Only 1 in 20 women deliver the baby on their estimated due date. This means only 5% percent of the babies are born on their calculated due date. So, take this due date just as an estimated date of your baby's arrival. Use this date to plan your activities around that date. In case if you have any queries, consult your gynecologist.
