  • You can try this:

    The day you conceive is exactly 2 wks pregnant.So you could count up 38 wks, also.

  • i just counted my 9 months up. of course add the month you got pregnant...but mine seems to be pretty accurate so far... i got pregnant in March around the 24. and my due date from the drs is Dec 25.. which is about right because i am 38 wks and everything is happening as far as contractions and thinning and dilation...but you can google that same question and it will show u the sites

  • Add nine months minus one week from your date of ovulation. If you just know the date that you had sex, and not the ovulation date, you can use that, too, but it could be up to 3 days early or 1 day late.

  • Estimated due dates are calculated from the first day of your last menstrual period.

    Your EDD based on your last menstrual period would be 40 weeks from that date
    (the first day of your LMP).

    Your EDD based on the date of conception would be around 38 weeks from that date
    (the day of conception).

  • I think the only way to really know the exact day of conception is if you had ivf. Knowing the day you had sex doesn't mean you know the day you conceived since it isn't necessarily that same day although that would give you a better idea then lmp.
