Junel Fe vs Isibloom??

So for two years I was on isibloom and it remarkably helped my period pain issues and even delayed my periods by a lot and it was all perfect until time went on and I went from 130 pounds a steady weight to 170 pounds. I’ve since stopped because I mentally and physically couldn’t take the weight gain anymore. But since stopping for months I’ve been having extreme irregular periods which is normal I believe but…. The only difference is that my last period was an entire month and the period I’m on now is almost a month and a half’s worth of pure bleeding, heavily some days too. I’ve since been diagnosed with anemia and am treating that with iron pills and I was on a blood loss treatment pill but due to how long I’m supposed to take it I can’t take it anymore for another month. They are recommending that I try Junel Fe can anybody give me any positive experiences regarding the weight issue and bleeding? I’m so scared of gaining more weight and sweating the way I did again. And if not any other birth control pills that didn’t cause you weight gain issues or water retention issues?? I’m not doing the IUDs at the moment so this is strictly talking about birth control pills.
