Question
Hello I'm 20 weeks pregnant, and the first day of my last period was september 3 and i have a 28 day cycle. I had unprotected sex with my boyfriend september 12th and 13th. Also im pretty sure i had cervical mucus on sept 12. Well me and my boyfriend broke up for a little and i had sex with another guy on september 21. i had a ultrasound the first trimester and i am due june 10th. I was wondering is it possible that my boyfriend is the father?

Answer
It is certainly possible, and I think likely, that your boyfriend is the father.  If you had sex Sept 13 and the sperm lived 3-5 days, it can put conception anywhere from Sept 13-18, which is certainly in the range of when conception occurred.

In order for the other man to be the father, you would have had to have ovulated later in your cycle than usual - Day 17 or 18.

It certainly isn't definite, but I think it's more likely that your boyfriend is the father.  The only way you will know for sure though is with a paternity test.

I hope that helps.
