Im 16 and im sexually active. I have been on the pill for almost a year, because my periods were very irregular. If sexually active, I always backup the birth control with a condom. I am due to get my period on the 17th. However on the 8th I noticed that I had some blood (not in my panties, but only when I wiped...Sorry I was trying to put it nicely) my doctor told me that it was breakthrough bleeding, since I had taken two of my pills late. The bleeding only lasted a day and was very light. It was a light red but then turned brown and stopped right after. I dont know why...But I am very concerned that somehow I am pregnant,since the bleeding really scared me. Could I be pregnant or is it just breakthrough bleeding or am I just over reacting???? Help please
