Desogestrel pill and irregular periods

I was on this mini pill for just over a year after switching from the combined pill. It slowly affected my mood to the point where my mood was constantly flat and I didn’t feel excited about anything. My libido was also very low. I felt a massive difference after stopping. Positives were I didn’t have periods often (every 6-8 weeks) and not much period pain. The 12 hour window to take the pill was also helpful when I sometimes forgot, as some other mini pills have shorter windows.

I was constantly bleeding and around the third month I started seeing a pattern emerging that essentially flipped my natural cycle: three weeks of bleeding, 4–5 days off, three weeks of bleeding, a couple of days off. It had a bad impact on my mental health, made me feel exhausted most of the time and killed my sex drive, ultimately leading to a breakup.

I wanted birth control to calm down or stop my painful periods. I was put on denestrogel as my gp wasn't comfordable putting me on oestrogen due to migranes. the first two weeks were great, then i started getting cramping but no bleeding. all that i saw was brown discharge for another week before i started bleeding. i didnt stop bleeding for the three months I was on it. completely ruined my sex drive as I was bleeding all the time and all of my underwear got ruined. I couldnt use a pad or tampon as the bleed wasn't heavy enough. it really started to affect my mood that i stopped taking it halfway through my third month on it because i was getting so distressed was really dissapointing as I saw so many good reviews on it and loved that it had a 12 hr forgetfulness window.
