Progestogen-only / Mini pill and heavier periods

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.

Ive been on this pill for over 5 months and I’m stopping. When I started about a month in I got horrible acne breakouts but I started using benzoyl peroxide and now it’s okay. I’ve had 3-4 periods and each one I’ve bled for weeks at a time so I am switching to a different one

My GP suggested I switch from Desogesterel to Noriday as I was consistently getting break through bleeding after many years of being period free. The first 6 months of taking Noriday were great, with a few days of very light spotting over many months. Then I started to get more regular, painful periods. I persisted with taking it, and after a few months of no period, it's been months of heavy, painful bleeds that last anywhere from 4 to 9 days at a time every 2-4 weeks. For the last few months I've been getting the type of period pain I haven't had since I was a teenager (I'm not in my mid-30s) - the kind that wakes you up in the middle of the night and stops you from sleeping. I'm coming off this pill today.
