Hey, I haven't gotten my period in 3 months now, at first I was wondering if I was pregnant but I took a test and it came back negative right away. I am concerned if this might eventually turning into me never being able to have children or of there is another severe problem going on. I am 18 years old and haven't had stress issues or take drugs. I have gone to a doctor and they keep thinking it's stress but I am not stressed. I would like someone's input on my situation. Oh and my last monthly visit was completely normal and lasted four days like the usual.
