Okay...so here's the story. So me and my boyfriend broke up in March and I hooked up with a guy I was kinda seeing on the 15th. I got back together with my boyfriend shortly after and I found out on 4/20 I was pregnant. My due date is 12/27 which makes it that I had sex and got pregnant around the first week of april. The baby has been small and less then 10th percentile this whole time and I've been measuring two weeks behind as well...do you think there is any way it could be the other guy? I feel like if that were the case the baby would be extra small then considering it's a two week difference. And I've been having ultrasounds every week for the past couple months and they have consistently been the same. I'm pretty positive it's my boyfriends but I just need some advice. Thanks ladies!
