I lost my virginity saturday night,(Using a condom.)and should have had my period that next Monday-Tuesday, but I never did. I am slightly worried that I might be pregnant. Seeing as I am almost a week late. Am I over reacting? Or should I give it a little longer? We have had sex 2-3 time more since Satuday also.(Using a condom everytime.) I was wondering if it is possible that since it was my first time that it would make my period late. Like maybe a stretch of the vagina or something. I also heard that It could be because of stress or being scared of being pregnet. That that would also make it slightly late. So my questions was... Can my period be late because it was my first time? Some advice, really fast. Would help this worried girl out.
