Just venting

Tmi just venting and if some one else has had this issue feel free to let me know if you’ve had a solution.

So my periods are awful I bleed for months at a time non stop. Longest I’ve gone was 4 months then my dr said let’s do a d&c he found polyps and removed them also side note I’m 25 years old. So anyways that didn’t help . So then we tried hormone pills that didn’t work and now we are trying birth control and that’s fine it’s a temporary fix. But when I stop taking the birth control I bleed again. Very long time and very heavy like clots the size of my palm . Idk what’s wrong with me. I’ve been to 4 different drs and they don’t seem to know. And it’s just frustrating. Because I do want a baby one day . But the birth control is just a temporary fix I don’t want to be on birth control my whole life .
