Possible conception dates don't match early us scan?
I had sex once on sept 22nd. I know sperm can live days after that. But I got a positive test on the 11th of October. I had my early us scan done and according to thay my "conception" date was the 7th of October. I know Sperm don't last that long. So with that being said them saying the max 5 days off on early us scans is different in my case? It would be off by 9+ days. How is that possible no one believes me

Hello to all who may wonder, I just found this on Mothering Forum:
(Just a drop of hope 4 us all!)
sperm can live up to 7 days in the right conditions. i teach fertility awareness, and though most books will tell you up to five days there has been studies that show sperm living to 7 days and longer. Several years ago there was an artical in Scientific America *i may have the title slightly wrong, called Sperm Wars (there is also a book) and it discusses how long sperm can live and the conditions they can live in.<br> I have a student who had sex nine days out from ovulation. She is due in December. I saw her chart, she ovulated nine days after the last time she had sex, and that was the only time they did it. She was more than shocked!<br><br> Kim
