'Iya. I'm 15 and have been having periods for around 2 & a half years. They're almost ALWAYS irregular, haven't had one for about 6 weeks now, but when I do have them, I'm literally crawling on the floor they're that terrible. Also, I feel like vomiting when I'm on. Maybe my eating habits have something to do with them being irregular? (I barely eat anything.) But I'm sure they shouldn't be this painful. Your thoughts will be appreciated, thanks. :-)
