I'm am now 16 going on 17. I got my first period when I was 12 for only one cycle. I didn't get it again till I was 15. When I was 15 going on 16 I got my period three times. I started birth control when I became 16 to help regulate my periods. After I started my birth control I had my period for one cycle, it's been 4 months since I've had my last cycle. I never get cramps, tiredness, irritable, mood swings, ect. My cycle lasts for 2-3 days then stop for a long amount of time. It also is never heavy or really light... I don't know really what to do I've been to 3 doctors about it and they can never find out what's wrong with me. Help please I'm really confused and frankly scared if this will affect me in the future with wanting kids.
