I'm 4 days late for my period. About a week ago I had unprotected sex. He used the pull-out method. I have woman's log on my phone and I log everything about my body. The day we had sex was a "fertility" day but it wasn't an ovulation day. I honestly don't know the difference. A few days ago my left side had this throbbing feeling. I felt it today too. Yesterday My nose started randomly bleeding. I've never had a nose bleed in my life. I've been cramping but still no period. And at the moment as I'm typing I feel I have to throw up. Ughhhhh am I pregnant. I feel like the chances are slim.
