A member asked:
My due date is 1 28 2015 based on a sonogram but my periods are not regular when did sex get pregnant?
A doctor has provided 1 answer
Week one of May, +/-: Sex would have been during the first week of May (plus or minus a week, if the U/S scan was done around weeks 8-11). The reason sex is estimated to be during week one of May is because conception (fertilization of the egg) is estimated to be May 8. These dates are always estimates, and is as good as it gets for U/S dating. The exactness of the dates doesn't matter for most women.
