Hormonal coil (IUS) and lower back pain

I've not had any significant side effects...so far. But the one thing I don't like is that I struggle to track my period. I don't bleed it bleed very little. Some periods are just spotting. In theory this is great, but the rest of my body is still experiencing a cycle and without the bleeding it can be hard to track. I still try to, but I'm about ready to give up. If you are like me and spent 10 years on the pill, this can feel a bit jarring. I'm on a hormonal rollercoaster that is normal but I'm not really use to it. My cramping is normal compared to before I had coil. I've had acne rosacea crop up and after a year of it I strongly thing it's linked to hormones but not sure how much the coil plays a part (though I did NOT have this before coil, I am also 40 and may be perimenopauseal). Insertion recovery was totally fine. Very little discomfort. However I was undergoing a minor gyno procedure at the same time and as a result got a general! Highly recommend should it be available. Won't lie, not sure I would have the coil again after this one....I'm still not sold in all honesty. It just emotionally felt evasive as a method of BC.

Overall my periods were regular but once I got the coil I had very irregular periods and extra cramping. I also have frequent dizzy spells and headaches since it has been inserted. And I've seen an increase in spots and body hair since starting with the coil

Extremely painful insertion. Blood loss continuously for about 3 months, bleeding everyday. Then periods became irregular, passing clots the size of my palm. Periods worsened after merina, when ironically merina was prescribed for heavy periods. Dermatitis caused by merina after 2 months. Told that results with merina are variable, and to wait and see. Not good advice considering the health issues and extreme blood loss caused by merina so far.
