Hi I am 13. I got my first period at 11 and they are excruciatinginly painful I go to school but I always need to have a high dosage of ibuprofen or stay home. I have random on day periods in the middle of the cycle which are always very irregular. I also have random days of pain but no period in my cycles to. I have pelvic pain only ever on my right side, cramps, back aches, fatigue and loss of appertite/ nausea. I only have a very distant family history of this condition any ideas if u think I do have it would be welcome Xx
