A member asked:
If my conception date is between may2 thru may10 when was my lmp?
A doctor has provided 1 answer
~2 weeks before...: Lmp (start of the last menstrual period) is about 2 weeks before conception, but if one already knows with some certainty what her conception date is, then the LMP date doesn't matter much (because the LMP date can vary +/- a week, depending on the length of her cycles).
