Hello, I got my first period when I was 14, now I m 18 years and 6 months old. My periods are still irregular.. for example this time it came 2 weeks late.. (I never worry about pregnancy as I m virgin). My period being irregular is one problem.. another one is that last couple years almost all my periods were very very painful (usually on first day).. it s so painful I cry, I can t walk, I m extremely nauseous and I vomit (sometimes multiple times).. this vomiting doesn t let me take pain meds, as everything comes out and I have to go through this pain until I don t throw up anymore and drug stays in my stomach.. and I also usually have diarrhea too.. I don t know what to do.. please tell me what you think about this situation... Thank you in advance 3
