so i was recently dating this girl.. we had unprotexted sex the day after her period ended (she usually has long periods so we were nervous) so we bought plan B the next morning... about a week later she got her period again (about 2 weeks early) we had unprotected sex on the first day of this period... I know that intercourse is generally safe during the first couple of days of a period but i guess i am nervous because this period was very early... am i overreacting? please help thanks
