I'm 14, Ive had my period since I was 10, and I missed this month. Or I'm very late. I've never missed my period before, except when my body was irregular at the beginning. Ive been under a lot of stress lately, and I heard it's normal to miss your period then, but I just wanted to make sure it's normal and that nothing bad is going on with my body. So is it normal or should I see a doctor?
