Progestogen-only / Mini pill and irregular periods

I have been using the pill for around 6 months and I keep getting irregular bleeding whilst taking the pill. I take my pill everyday but somehow seem to bleed anyway it’s not spotting as people say it’s heavier like a normal period. It changed my mood within seconds and keeps giving me my Period every 2-3 weeks.

Started taking Slynd to help with heavy periods and cramping. First month was fine, felt a little extra emotional. Second month I got my period two weeks before I was supposed to and I am still bleeding after two weeks. Crazy cramping, clotting, heavy bleeding. Had a day or two in there that was light or medium. Poking around on Reddit this seems quite common. Most people stop, not a lot of folks talking about continuing and it levelling out. Waiting to see.

I went on desogestrel twice. The first time I noticed it made me cry extremely easily, and I bled pretty much constantly for 9 months. Then I came off it. When I tried it again for a few months, I had a similar experience, with the added side effect of being so hungry that if I wasn't constantly snacking I was insanely nauseous. Ultimately, it was the bleeding that made me stop it.
