Hi,my last menstruation was August 30 2014,and I had sex with my bf September 7 2014,I was wondering if am I fertile at that moment?and the first round of our intercourse was, he use condom,and after cumming he removed it and it was around 2-5 minutes we have that second round of intercourse,but this time without condom,,he didn't cum inside though,,but it really bothers me that there is a possibility that there still semen on his penis that might got into me,and after 1-2 hours we did it again w/out condom again,,, I was so afraid so I took nordette 23 hours after we did that is it still effective?how long for a sperm to meet an egg,?
