I had unprotected sex on the 21 multiple times, I had sex on the 23 and he pulled out. I took an ovulation test on the 23 a hour or so afterwards and it was positive... I had unprotected sex on the 27 at about 4 am with a DIFFERENT person that didn't last very long (I stopped it, was drunk) and he told me he didn't precum and I did lots of research that says precum doesn't have sperm in it unless you came recently and didn't pee (as lee kills sperm) I'm now due for my period in a day and I'm wondering is there ANY possible chance it could be the second persons child?
