Best progestogen-only / mini pill

I'm in months 2 and hoping things get a little better. Pro: No periods or period pain/endo pain! (HURRAY) And no weightgain (which i had on another pill) Con: I'm feeling down, sleep bad, hair loss, forgetful, spotting, BV, vaginal dryness, heart pains and rising anxiety. I want to give it a month extra or so but the side effects are getting me down. This is the 2nd pill I've tried this year. The first one was a combined pill but made my uterine lining super thick and that gave me massive cramps and hurt. So let's see but kinda sceptical.

I love this pill. I was struggling with mood and physical symptoms around pms, I have tried several oral contraceptives intermittently over the last 15 years but had other side effects to them, I was using a Kyleena coil which worked really well for contraception and period control but as this did not stop me ovulating, PMS became my main concern. I tried Slynd when it became available in the UK and I love it. My cyclical mood, bloating and skin issues have basically completely resolved and the longer missed pill window works much better for me.

I had my first postpartum period without any birth control and it was a bit heavier than normal (pre-pregnancy comparison) but not too bad honestly, the cramps weren’t horrible either. Then my second period I had been on Slynd for about a month and it was HORRIBLE, I’m a medical nurse and I have an relatively high pain tolerance but I considered going to the hospital. The first night I was having multiple medium sized clots that my coworker said looked like it was uterine lining, heavy heavy bright red bleeding and horrendous cramps that made me want to vomit. Plus my uterus was contracting so much I think I went #2 like 5x that day alone. Day 2 was slightly better with slightly less horrible cramps but still relatively heavy bleeding and some small clots every hour or so. Now day 3 and I’m heavy bleeding still and now have some sharp lower abdomen pain especially when in the motion of going to sit down or stand up. I’m hoping this stops soon because this has been the worst period I think I’ve ever had and pre-pregnancy I thought I had some pretty bad ones. I don’t think I will be continuing this birth control
