Ultrasound

Would doctors be able to tell paternity for sure if a person had sex with 2 different partners in 3 weeks through ultra sound?

Yeah everything has been right on track with #2. It really sounds more terrible than it is. It's not that slutty lol. I had a break up with a bf then a drunkin night. Plus I'm measuring 2 1/2 weeks smaller than I should be. Thanks for your advise and not your critizism

I agree with NicoleW09. Women are least fertile right before their period, so #1 is probably out and #2 is much more likely to be the father.

You usually don't ovulate 5 days before your period. So, my guess would be that it's guy #2's. Especially if your ultrasound shows the baby measuring on the right track according to your last period.

I asked the ultra sound tech and all she told me was that I had my period then ovulated 2 weeks later. Ps guy #1 was 5 days before my period. Which came and was normal, then #2 was 2 weeks exactly after my period. I have a normal 28 day cycle. Just wanting some second opinions

If you don't know when you ovulated, a U/S might help narrow down when you conceived, although it is not 100% reliable and might be off by a few days. A DNA test when the baby is born is the most certain way.
