conception calculator?

Question

my last menstrual was on june 19th. on july 7 i had a little bit of spotting. nothing else yet. i did the online conception calculator and he said conceived on july 3rd. but i am thinking it was on the first, since i am pretty sure i had implantation bleeding. so my question- could the conception calculator be wrong?

Answer 1

Conception calculators don't really take into factor that sperm can live up to 5 days or that you may have ovulated earlier or later than the calculator says. According to the calculations i should be 28 wks now but every ultrasound i have had puts me at 27 wks right now.

Answer 2

Not all women ovulate at the "perfect, normal" time. On a 28 day cycle the normal ovulation time is 14 days after the first day of your last period. There is a window around ovulation that you can get pregnant (anywhere from 1-3 days) due to the fact that healthy sperm can live up to 48 hours inside. Even though I have a normal 28 day cycle, I ovulate by the end of the first week after my period, so everyone is a little different. Most of the conception calculators calculate using the "normal" ovulation time. I hope this helps.

Answer 3

Could be...Sperm can live inside you for up to 7 days so even if you had sex on the just say 4th you could have not gotten pregnant until like the 8th
