I've Had My Period 3 Times In A Months Time.

I've had my period 3 times in a months time. Each time I've bled harder. This last time I went thru 3 boxs of super plus tampons having to change it every 30 mins. The cramps and pain was unbearable and all I could do was sleep. Now that I'm not bleeding I still have full blown cramps and pain with a little spotting evert now and then. But it feels as tho something is bulging in the entrance to my vagina. I can just tell some things wrong. Any suggestions as to what it could be??
