Im 17 years old and the last two months has been a struggle cause i never know wbn im going to need a tampon. Last month i was bleeding for about two weeks. Barely anything was coming out it was very light with a rownish tint. It finally stopped. Then four days later i have an actual period. It was heavy in flow. Then i got off of it after about eight days. I have been off my period since april 6th and three days ago i start bleeding again accompanied with these terrible cramps. Could there be something wrong?
