Progestogen-only / Mini pill and vaginal dryness

Started this pill as I had horrendous migraines on Rigevidon. Was excited to start the mini pill and to not have bleeds in between pills but was I wrong. The first 5 months I’ve had random bleeding- which I expected (but not for over a week straight) I’ve also been heavily dizzy, nauseous and have had 0 sex drive which has affected my relationship heavily.

I've only been on this pill for two months so there's a chance this may calm down after the full adjustment period, but the side effects have been interesting. Most notably, my cycle has gone from around 35 days to 13 days, and I have been having a period every other week. The first two periods gave me hope because they were significantly lighter - to the point where I was questioning whether or not I should even log it as a period - and painless. However, the next three periods I've had so far have been gradually getting heavier and I'm getting more cramping. It's weird though because, for most of my period it's still quite light, but on around the second or third day, I do have a few hours where it's quite heavy and crampy, then it subsides again and the rest is light. I had spotting between the first three periods but that's stopped now. Other than the annoying cycle changes, I had a constant lingering headache for the first two weeks, I'm getting more acne than usual, and some vaginal dryness before my period. I don't know if this is worth staying on as I'm only on the pill to manage my painful and heavy periods. Current plan is to finish my three months' supply and take it from there.

Hugely helped with period pains (no periods!). Has evened out any emotional changes - I feel very stable. No nausea like with the combined pill. Lost weight (as well as boob!) but unsure if that's compared to when I was on combined pill or baseline.
