HOW ACCURATE R ULTRASOUND RESULTS AT 24 WEEKS ?? NEED ADVICE PLZ ):

[yaya07]

I was wondering how accurate can an ultra sound be around 24 wks when it comes down to figuring out when was ur last menstrual period & date of ovulation & conception ?? I didnt know when my last period was since i was on birthcontrol & did not have periods bkus of the method i was using. But after an ultrasound at around 24wks the said my lmp was Oct 6,2012 & i conceived Oct 20,2012. I had sex with a friend sept24. Unprotected but he  did not ejaculate in me. We never did it again. But i did have unprotected sex with my bf alot in October. What r the chances my friend is the father ? & how accurate could my ultrasound results be !? Please help im losing my mind over this !! I dont want my friend to be the father !!! ):

My ultrasound at 19 weeks was only 1 day different from my expected date of conception.

All mine have been dead on!!! They all agree with me on my dates as I was trying and kept good records!!!!!

During my last pregnancy, my doctor confirmed the dates at a 6 week u/s. And they reconfirmed each u/s thereafter. It was very accurate.

The US are very accurate. If you got pregnant in September you would be further along. It looks like your bf is the father. Try not to stress you can also get a dna test.
