the only reason women ask questions like this as to the exact date they conceived is only beause they dont know who the father is beacuse they had unprotected sex with more than one guy around the same time
and you CANNOT GO BY HOW LONG SPERM LIVES TO DETERMINE WHO YOUR CHILDS FATHER IS (if thats what your looking for) because if you had sex with more than one guy around the same time....it could be anyones child so you would have to get a dna test done
IF
you are asking so you can just find out when you conceived just because its pretty good to know....your doctor could tell you that or you can take your due date your last period and going on google and do a pregnancy calculator
right thanxs bet that was a weird question t ask thanxs alot x
no its 72 hrs or 3 days thats why you take the 72 hr pill and when your trying to concive they tell you to have sex every 2-3 days to keep the swimmers toped up, so depending on your womb they will live 2-3 days at the most.!!!
hey they sperm can live 5-7 days before it dies :) congrats on the new baby
I think it is 3 to 5 days.
