How accurate is conception dating
Do you think there's a big chance that the 2nd man could potentially be the father?I am hoping the first man is indeed the father, because we have been friends for years, and it would be alot easier to handle. I guess I just want some confirmation that these ultrasound dates are accurate.I have really been stressing over if it could be my friends.But I've been doing the conception calculators and they all say I conceived around may 3rd - may 9th ..which doesn't make sense to me because the ultrasound gives the exact fetal age of the baby or does it add 2 weeks..I discovered I was pregnant unexpectedly, and went to have an ultrasound on May 23rd.Due to having wavering periods, I never really keep track, and therefore I don't know when my last period was.Her first ultrasound was 2/20/2012, dating her at 12 weeks exactly with an due date of 9/3/2012.The doctor told her that her conception was 11/29/2011. i just want to know could the ultrasound predicting conception date be wrong, and is there a chance that i could be the father?
I guess my point was really that it is possible that it is your baby still given the dates, however there are other things impact these dates such as average cycle length, which is generally 28 days, but can be shorter or longer depending on the woman.
I didn't think anything of it, because I am almost 38, and this has never happened to me before.
