Desogestrel pill and period like cramps

I had always suffered with very minor anxiety, however once I went on this pill I was a wreck. It was like I became a whole different person, I was irritable, mean, and I was constantly upset. In the space of a month I went from a D to and E, and I gained weight like I never have before around my lower stomach. I had always been rather skinny around there, but even after 2 years of not taking it, I have never been able to return to how my body was beforehand. The first 2 and a half weeks were normal, but after that I bled consecutively for 9 weeks, with a few 16 days staggered in between where I only briefly spotted.

I have mild adenomyosis and pcos, i wanted to try out a POP before a method with estrogen or inserting something I need a healthcare specialist to take out. In the end I couldn’t stick this out for the 3 months that they advise. Since starting I’ve had different side effects. The first week was bad reflux, the second week I had leg cramps, then I had 3 weeks of a constant thumping in my head with a headache that comes and goes, I was referred for an MRV and told to stop the pill. It’s been a week since I’ve stopped, every day the thumping has gotten quieter, no sudden “hits” in my head and today it’s finally gone. For whatever reason, it’s not for me. I will admit it did lighten my bleeding and it looked like it was on its way to stopping, but it never actually stopped completely before the headaches started.

My side effects were all fine (basically non-existent) on Desogestrel besides very regular bleeding/spotting. The first 2-3 months were okay with a period-like bleed every 3 or 4 weeks with cramps too (although a lot less painful than my usual periods). But then the frequency increased. I tried to wait it out but after 7 months I was still experiencing spotting/bleeding every other week. Besides this I would’ve stayed on it and had no other problems. I’ve now changed to a combined pill which will hopefully make me bleed less.
