My boyfriend and I had sex yesterday (04/21/09) - it was not our first time. We used a condom, and he pulled out before he ejaculated so nothing was inside of me. But later, I found out that he first put the condom on backwards, and then flipped it and put it on the right way. I did not know about this at the time and now that I do, I am absolutely terrified that I might be pregnant. I know that I am probably being overly paranoid about this, but I was feeling apprehensive about my decision to have sex in the first place, and this has just made me feel even worse about it.

My boyfriend does not have any pre-cum to begin with and never has - so, there was no visible pre-ejaculate on the condom. He told me that the tip of the condom never touched his penis because there was air in the tip and he caught his mistake before attempting to roll it down any further. I read elsewhere that if he had not ejaculated before putting on the condom and if he had urinated soon before, that the chance of pregnancy will be even less likely because the sperm from the previous ejaculation would be washed out with the flow of the urine - he had not ejaculated prior to this and he had urinated right before as well.

My last period began on April 6th, and I have what I believe is around a thirty day cycle. I have not been sexually active for very long, so I never felt that I had any reason to chart my periods before, but now I wish I had because I'm afraid that I might be ovulating and that has got me even more worried about this. I know that the chance of me being pregnant is very small but regardless, I am so scared. I am extremely stressed out right now over this and a multitude of other things. This scare has taken over my mind and I can't bring myself to concentrate on anything else. Please, please help me if you can. I need some sort of reassurance because this is the only thing I can think about. Thank you in advance for your help.
