Progestogen-only / Mini pill and irregular periods

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 really wanted to like Desogestrel. Initially, my skin was the worst - so oily and immediately broke out in painful acne. This quickly subsided after about 2 weeks. For 3 months, my breasts were so enlarged and sore all the time. I noticed around the 3 month mark that I was experiencing vaginal dryness too. My periods have been totally irregular - since starting Desogestrel in May I've had 10 periods. Many of these were trigged by intercourse. The volume of blood and the level of pain was variable for every period, making it hard to predict. The final straw for me was I started losing my hair around the 5-6 month mark. My hair is noticeably thinner on top and the ends are ruined / look awful. The only positive for me has been that it made me more energetic and have a better / more even mood. It did has not affected my sex drive and I gained a negligible amount of weight.

My periods are much lighter now, I probably bleed for about 3 days in 3-4 months - it is irregular though unfortunately so I can't predict when it may occur. My mood is much more stable than it was before and whilst using other hormonal contraception. I have been getting much more increased sweating recently though and had not made the link that it may be connected to the pill before seeing it on the Lowdown website. I have had a really positive experience with the mini-pill, especially after having used the implant before.
