How the due date is worked out
From the first day of your last period
A pregnancy lasts about 40 weeks, or 280 days, counted from the first day of the last period, not from the day the baby was conceived. That is why, by the time a test turns positive, you are already counted as about 4 weeks pregnant. The 280 days assume a 28-day cycle. If your cycle is usually longer, ovulation tends to come later, so the due date moves later by the same number of days; a shorter cycle moves it earlier. A 32-day cycle adds 4 days, a 25-day cycle takes away 3.
From conception or an IVF transfer
If you know the date of conception, the due date is 266 days after it. After IVF the date is exact: 261 days after a day-5 embryo transfer, or 263 days after a day-3 transfer. In every case the weeks are still counted the usual way, from 2 weeks before conception, so your week matches what your doctor says.
Why your scan may give a different date
Many women are not sure of their last period, cycles vary, and ovulation does not always come on the same day. An early ultrasound scan measures the baby and often gives the most reliable date. If your doctor gives you a due date from a scan, use that one: choose "My due date from a scan or doctor" above, and the weeks and checkup windows will follow it.
What "full term" means
The due date is an estimate, not a deadline. Few babies arrive on the day itself. Full term is from 37 to 42 weeks, and a baby born before 37 weeks is early. That is why the calculator shows the dates between which most babies arrive. If you pass 42 weeks, contact your hospital or doctor that day.
Checkups in Bangladesh
Bangladesh’s schedule is at least 4 checkups during pregnancy, at about 16, 24–28, 32 and 36 weeks. Many doctors advise 8, at about 12, 20, 26, 30, 34, 36, 38 and 40 weeks. Your doctor sets your schedule. The calculator turns the weeks into dates, and the calendar file puts them in your phone with a reminder the day before.
The date in the Bangla calendar
Many families, and many grandparents, count in the Bangla calendar. The calculator gives your due date in Bangladesh’s revised Bangla calendar too, the one that starts every year on 14 April with Pohela Boishakh, so you can tell the whole family in the dates they use.
Questions parents ask
How many weeks pregnant am I?
Count from the first day of your last period: the number of whole weeks since then is your week of pregnancy. Enter that date above and the calculator shows it as weeks and days, for example 14 weeks 3 days, with your trimester.
How accurate is a due date?
It is an estimate. Few babies arrive on the day itself: most arrive between 37 and 42 weeks. A date from an early scan is usually the most reliable, so use the date your doctor gives you.
Should I use my period date or my scan date?
If your doctor has given you a due date from a scan, use that one. Choose "My due date from a scan or doctor" and enter it; your weeks and checkup windows will follow it.
What if my periods are irregular?
Enter your usual cycle length if you know it, between 21 and 35 days. If your cycles vary a lot or you are not sure of the date, treat the result as a rough guide and ask at your first checkup about a scan to date the pregnancy.
When should I have my first checkup?
As soon as you know you are pregnant is a good time to see a doctor. Bangladesh’s schedule has the first of at least 4 checkups by about 16 weeks; many doctors suggest one at about 12 weeks. Your doctor sets your schedule.
Ramadan falls in my pregnancy. Can I fast?
The calculator only shows whether Ramadan is expected to fall in your pregnancy, and in which weeks. Whether to fast is a decision to make with your doctor before Ramadan begins; many families also talk to their own scholar.
This calculator gives general information, not medical advice. For health worries, talk to a doctor; if someone is in danger, call 999.
