Period for the 97th day

Bria

What do I do to stop my period? This is a constant thing for me for the past 3 years. I’ve gotten tested for std’s and BV etc and everything comes back negative. I have a tilted uterus so an IUD is not an option. Also nexplanon gives me ovarian cysts, so what birth control should I try now? And how can I get off my period because I’m tired of bleeding 😢
