Hi I have 18 years and I am sexually active since I was 16. My period started on my 12 and it was a little painful but passable. however, began to increase in amount of blood and clotted for my 17. Unfortunately increased pain and clotted. they were to large and seem a like our little finger of the hand. The concern is that these increased clotted a month ago and before this month no period gave me pains in the abdomen (right side well below). I went to the gynecologist for the first time and just said that's normal. you believe? help!
