Pull out method.

Lillian

So, my fiancé and I had unprotected sex on 6/20 & he ejaculated quicker than expected & then pulled out. It just so happened to be my ovulation day as well. About 2 days later I started getting bad stomach cramps & diarrhea for about 12 straight hours. I was also nauseous. I could be paranoid. But what are the odds of me actually getting pregnant on my ovulation date?
