So I am 18, just graduated high school..I haven't had my period since February. Mid March I took a test and it was negative. So I was relieved and figured I'd just wait..so towards the end of March I took two more tests. Also negative. So I figured maybe I've missed my periods because I'm stress but without my period I can't not stress. I've been w my bf for four years and he feels like if it's true we are f ups. Idek what to do now. I have an appointment in a couple of days but what could it possibly be.
