Hormonal coil (IUS) and sweating more than usual

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.

Not 100% sure what to think yet. Enjoying not having to worry about administrating my contraception as it’s in there and working. However I am having unpredictable spotting, some emotional mood swings and often being bloated.
