Worried about dates

[newmother123]

So here it goes. My dates for my ultrasound are matching up with when my boyfriend and i had unprotected sex with ejaculate. However, 12 days later I had a fling with someone while drunk. He said we didn't finish, and it was 2 days before my period was suppose to start, but for some reason I can't stop thinking about the possibility that the baby may not be my boyfriends. I had never done anything like that before and I'm just so scared. My baby is growing at a healthy rate according to everything, but are they ever wrong? Can the ultrasound at 6, 9, and 12 weeks be 12 days off?

I think you are okay and if u had sex with this other guy 2 days before your cycle was due ovulation had already come and gone.I understand what youre saying and why youre afraid but you should be good and the baby is more likely your boyfriends..... Just please never get drunk again especially when you and another party cannot handle yourselves. Good luck new mom and here's to a healthy baby

Not 12 days off at 6 weeks.

I cannot stop obsessing over dates. Everytime I look at my boyfriend I just feel like garbage. Like a terrible person for the mistake I made. I just want to know if there is any chance that I could have gotten pregnant that late when I have regular cycles every month?
