I am 9weeks 2days. My due date is April 2,2018. me and my partner has always had unprotected sex. Pretty much every other day it seems. I found out he had an affair on me and it crushed me. I wanted to get even and I had unprotected sex July 10th. That was the only time we had sex. He did use the pull out method and I know that's not 100 percent safe. I have pondered on this for a min now. I just need answers please. Other than a blood test.
