Anyone else have this problem?

Does anyone else deal with this? I have been to doctors multiple times over this in the past few years but they never tell me what’s wrong and just put me on medroxyprogestirone (I think that’s how you spell it.) and it does stop the bleeding for a short time and then a few days later I start bleeding again but it’s extremely painful and heavy and last about a week after that my periods are gone for months at a time and then the cycle starts all over again.
