Okay so recently i had unprotected sex the day after i ovulated (i ovulated july 22) but my boyfriend and i stopped so he could finish himself. Then i did it again on August 3, which was 3 days before my period was supposed to start, and this time again my boyfriend finished by himself to not risk anything. Since we were both freaked out i took a plan b a day later after the second time, but my period still hasn't came. I'm having cramps but i'm scared it's just my mind telling me i am. i don't know what to do, please help me.
