How many weeks pregnant am I?

Pregnancy FAQs

Weeks of pregnancy start from the day of conception. To know how many weeks pregnant you are, you would need to know the date of conception, and simply count the number of weeks from that day.  It’s quite common that you may not know the exact date of conception, and in this case the counting usually starts from the first day of your last period, and add 40 weeks (280 days) to this date to get your estimated due date.
