I had sex with an ex boyfriend because my boyfriend and I “broke up” but it only lasted a few days.. with my iud placed in and I was on my period around 1-2am. I removed it 16-17 hours later that same day, not going to explain why. I started having sex with my boyfriend regularly after that and now I’m pregnant. Don’t know how many weeks, I’ve gotten mixed answers from 2 different clinics. I want to know the possibility of my ex being the dad?

Any answers would help
