Progestogen-only / Mini pill and spotting

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.

I’ve had nothing but cystic acne, heavy bleeding for 2+ weeks at a time, hair growth is still the same rate if not even worse.

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.
