Progestogen-only / Mini pill and more regular periods

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.

Its regulated my periods, made them lighter and helps with PMDD I still ovulate most months on norgeston but thats normal apparently, Im not too worried about it, i have noticed my boobs have gone up a cup size or two but compared to desogestorel its been amazing, i had a period for 5 weeks on desogestorel then i was off for 1 and back on for 5 etc now im every 28 days like clockwork

gradually feel more down and down and my periods never stop i can bleed for 30 days then have a 3 day break and it’s back
