Me and my boyfriend use the pull out method and one day he pulled out a little late, so I took plan b. I got my period one week later. About 3 weeks after that we had unprotected sex again and he actually ejaculated inside of me. So, I took plan b about 6 hours later. That was on Aug 9th. My period was due on Aug 17th. It is Sept 11 and I still haven't had a period. I have no pregnancy symptoms or even period symptoms and I feel fine. I'm just extremely worried. Please help.
