So, my period last month went from October 12-17 I have very consistent cycles, ranging from 28-30 days, on the 21st of October I had unprotected sex with my ex, on the 22nd I met up with my boyfriend to talk since we split up, we had unprotected sex that night on the 22nd and got back together, then on the 25th we had unprotected sex again. it says according to my app that I ovulate on the 25th, the same night I had unprotected sex. So is my current boyfriend the father, or should I get a paternity test?
