Progestogen-only / Mini pill and spotting

I started the POP because I had a few migraines with auras on the combined pill and had to stop this. When I started the mini-pill my periods became very irregular. However, I went on the combined pill in the first place because of my irregular cycle so this may just be me. I have noticed my periods are lighter but I never had heavy periods anyway. I have had a few cases of spotting for 2-3weeks after getting my period but this hopefully seems to have settled now after 5/6 months and I get a 3-5 day light period. My skin flared up with bad hormonal acne about 3/4months after I started taking the POP and hasn’t gotten any better. Another reason why I went on the combined pill initially was to help with acne so I feel this has regressed since starting the mini-pill. Also, I have had some horrific cramping at random times. A couple of times has been a whole week of painful cramps but again this hopefully seems to have settled down a bit after about 7/8 months of taking the POP. Overall, I’m not happy with the side effects I’m experiencing, especially my skin, and am considering trying the hormonal coil, but will give it a full year on the POP to see if my body starts to settle.

I was prescribed generic Desogestrel mini pill to treat my adenomyosis. I was only on it for a couple of weeks, but I couldn't cope with the symptoms. Daily bleeding and bloating but more worryingly, horrendous nausea, dizziness and migraines. Also had swollen tender enlarged breasts.

Was put on this to help with my severe period pains. It has helped but I'm not sure it's worth it with the side effects. I can honestly say I am depressed. I have zero motivation, zero energy, zero inclination to do anything I used to enjoy. My sex drive has disappeared it doesn't matter because I've bled for the majority of the time I've been taking it. I want to stop but my GP won't try me on anything else until I've been on this for 3 months.
