I'm 39 weeks when did I get pregent?

... 39 weeks ago?

There is a 'due date' calculator on babynames.com on the left hand column. If you put in the first day of your last period, it will tell you your conception date and when you are due.

The conception calculators work really but you could ask your OBGYN as well they would be able to tell to the day almost.

And yeah, if you know you are 39 weeks just use a normal calendar and count back.

Hang on... I just read that again... surely that means you are 3 weeks overdue??

Pregnancy term is 40 weeks.

Just wanted to interject that if you are concerned with who fathered the child using a due date calculator to determine when the child was conceived is not an accurate tool.

If you suspect two different men, please do the right thing and have both of them tested. Children are a lifelong financial, emotional, psychological commitment, do not obligate someone based on a due date calculator.

If that is not the reason, I apologize, but primarily that is the only reason that people want to determine the date of conception.

Whoops, not thinking, sorry... very late here...
