Progestogen-only / Mini pill and body hair getting darker

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.

When I was on it I was really pleased with how it was going. I felt balanced due to no periods and lack of mood swings etc. It felt great to not have periods and have that interruption on my life each month. What I didn’t realise until after I came off it after many years of using this pill, the implant and another pill previously was the affect it had had on my arousal/libido, I had always put this down to anxiety, but I feel very confident in saying now that having a true cycle has made a huge difference to this. When on the pill (especially the mini pill) I felt broken as to why I didn’t ever think about sex, but that changed almost instantly when I stopped. I wish I had known how much this would have impacted this. I would use it again, but I would be cautious of this change.
