I'm 16, and I started my menstrual cycle when I was 12. The past couple of years, my periods have been extremely painful. I've had to miss school, and stay in bed all day, the first day it starts. My cycle has always been irregular, with my period lasting 5-7 days and usually coming between every 4-5 weeks. I've always had trouble with bowel movements when I'm menstruating, and it's often very painful. Recently, I've been noticing pain during ovulation, even worse than the cramps I get when I'm on my period. I can hardly stand it; at some points I am on the floor rolling around because I'm in so much pain. I get cramping in my lower belly, near my ovaries, and also in my upper thighs and lower back. Recently, I've noticed I get cramps a week before my period starts, and I always get awful menstrual like cramps when I exercise. I haven't been diagnosed with endometriosis, but it runs in my family. My grandma and aunt have it. I haven't been seen by any specialists, but I'm wondering if maybe I do have endometriosis. I know I'm very young, but I've read that doctors are beginning to see it in younger girls. I'm not sure what it is, but it's frightening, and I've been noticing my periods have been getting more painful. I'm not sure if I ought to be seen by a specialist, since I'm so young, or if I should continue to cope with the pain. I take Advil for it, often as many as 9 a day. I'm 5"8 and 105 pounds, and I'm wondering if my weight has something to do with it? I'm not sure. Feedback or advice would be much appreciated.
