So me and my husband always pull out. I personally do not use birth control. We tried for over 2 years to have my daughter. So on a whim we had sex 3 separate times and he came inside of me. I didn't track ovulation or anything. The third time, I spotted after sex. I thought nothing of it because my period was due three days after that. My period didn't come and I'm pregnant! What are the odds? Lol.
