Hello.. I Am Rachel And I Am 15 Years Old.

Hello.. I am Rachel and I am 15 years old. I had my period a week ago and now I am bleeding again. It's the worse it's ever been. With cramps so severe I actually vomited and nearly fainted. The blood flow is so heavy that I filled up a super plus tampon in 30min. I am still a virgin and had no forms of sex. Please help
