Hi I am 16 and I haven't had my period for 3 months and I have taken 3 pregnancy tests and they have all came out negative.I am on birth control and have been sexually active a week before I didn't start my first period out of the 3.I don't feel any different, I just have been peeing a lot and spotted once or twice.I have talked to my parents and they said its normal.but I don't think it is.
Please help!I need to know if I should be worried about this.
