I've had my period for 3 and a half years now and the first few periods were painless and light but then when I turned 13 they because ruthless and extremely painful not to mention so so so much blood. My parents and Doctor said I'm fine and I'm on a perscription pain medication for my crazy cramps but lately I have been very well let's just say constipated, every hour or so I need to make a trip to the bathroom and I'm in High School! Somebody please tell me what's wrong with me!
