So I've never really been regular except for last year I was very rugular. I guess you could say. I never thought anything of it, just that it was puberty and it would become more regular as I get older. I turned 15 this year and been having periods since I was 13. I'm starting to worry that maybe I have pcos but I don't have the symptoms as many others do. I don't grow or loose hair and my skins quite clear, I'm over weight but I feel that is of my own doing. I also feel that my absence of menstruation is due to stress for I've become very stressed since January, but I don't know if I'm really stressed. I saw someone post in this group that they've miss their period every spring but I can't recall last year's spring being irregular or not. Could it possibly be that I have PCOS?
