Progestogen-only / Mini pill and period like cramps

I was moved from Yasmin to Cerazette by my gp due to my blood pressure being affected. It's my second month and I hate it. I had no side effects from my other pill and was on it for 4 years. My periods used to last 4 days and were regular. Now I'm on day 12 of a very heavy and painful period. Even when I wasnt bleeding I was spotting. My skin has gotten worse, constantly oily and my hair is so greasy all the time. I used to be able to wash my hair once a week (curly), now I have to wash it 2 or 3 times a week due to build up of oils. I have also started losing a significant amount of hair Everytime I brush and wash it. I also lost all appetite and have lost almost 4kg. Also I've never struggled with body odor until now, no antiperspirant helps to prevent it and it's very embarrassing. My entire lower back and pelvis aches and I feel really depressed and fatigued.

I switched to Slynd having previously taken Hana but been unsatisfied with the experience, and can't ask much more from it. I found that my mood almost immediately improved, and I continued to experience a more stable mood. I do occasionally experience headaches around the time of the placebo break, but this was normal for me without medication anyway, and it's better overall to know exactly when this will happen. In my first month taking Slynd, I did experience a lot of bleeding - but I had been bleeding constantly on Hana, and I think this is down to the Hana pill insufficiently thinning my uterine lining and then the Slynd pill starting to work correctly, meaning I had to shed the build-up. In the second month I didn't bleed at all. After that, I did start to bleed in the placebo break, and experience increasing spotting between breaks, but this was still a very light amount overall (I am starting to think I might have just been a heavy bleeder to begin with!). After around 6 months of taking the pill, I did have one day of very heavy bleeding at the start of my Placebo break. From the next day I returned to having no spotting and a lighter bleed the next month. I am happy with this cadence personally, and I do suspect that someone who already bled lightly wouldn't experience this at all.

Genuinely hate this pill. I have always experienced acne but rarely on my body until now. My back chest and shoulders are covered. I have had bleeding about 2 times a month with no changes to the pain scale. I have gained a bit of weight. Where on the last pill I was on I had lost some. Which certainly effected my already down mood. Just is not working for me.
