Period from hell

So I've come to the conclusion that my period is the devil himself. It's irregular. I spot randomly for like a week or week in a half stop for s few days then my period comes. I've gone to the doctor I've been tested for everything. Std's, fibroids, pregnancy, hypertension, PCOS, and on and on and on... I'm healthy as an football player so wtf is the deal? I was on birth control for many years and just recently came off because it was making me sick not helping regulate this bipolar bs going on. Now I feel like it's trying to regulate its self but trying to change and come on my wedding day in nov when I planned around my period. Is there anything that can be done naturally to regulate this shit? I'm so frustrated with it I seriously want a hysterectomy but I also want two more babies.. I diet and exercise regularly nothing too extensive.. What more can I do? Helpppp
