Hormonal coil (IUS) and headaches

I had it put in at the end of January. Insertion wasn't fun and did hurt but no worse than the period cramps I used to get. Did spend the afternoon in bed. First few months were ok, some period pain but less than before and lighter periods. But as a few more months have passed I've been getting more migraines again. Also my body hair is more noticeable. My mood is mostly stable except now when I'm ovulating or period about to start, I get very irrational and angry. My last period was heavier than I would have had before the coil but hoping that was just a blip. Have also been spotting constantly the last 2-3 months.

I got the coil fitted to control heavy periods with contraception as a bonus. I’m aware I might be still in the settling down phase, this is my experience so far. Fitting was uncomfortable but I’ve had 3 vaginal birth so nothing touches that! Cramps for a few days but settled down. So far I have been bleeding most of the time since having it fitted, not heavy, light, but constant and irregular patterns. Very annoying. Low self esteem and low mood. Weight gain, despite being more physically active and eating healthily. Increase in headaches and migraines. Generally unimpressed at the lack of connection with healthcare professionals and Mirena coil users. So many women reporting poor experience yet doctors aren’t relaying this information. Will be having it removed. I choose control over my body over convenience.

First 6 months is an adjustment period so I had plenty of headache and feeling sick but after a while my body used to it and I am fine. 100% contraception effectiveness and no heavy period.
