Hormonal coil (IUS) and spotting

I've had a mirena coil for about 7 months now. Before getting it I had severely heavy periods. Most months I got a bad migraine. My iron was low. The GP didn't suggest anything to help with the heavy periods/monthly migraines/low iron. However when discussing contraception mirena coil was suggested. (I'm 40, have had 2 children). I was wary to mess with my hormones but the doctor said it could calm down my periods too. It was a long wait (almost 12 months). As soon as I got it I haven't had such heavy periods. Migraines haven't been an issue and my iron levels are back to normal. I haven't noticed any mood or weight changes. I've been happier and healthier because I haven't been dealing with the bad periods anymore. My periods are irregular, but very light. The only negative is a couple of times I've had stomach cramps, quite painful ones, they've gone away in under a day. There has been no follow up with a health professional. It would be nice if they did this to reassure everything is normal and ok.

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.

Year 1 was a lot of hormonal changes, strong random cramps and spotting (i had to get the position adjusted slightly about 8 months in), but the effect on my periods was almost immediate. Regular lighter periods with reduced cramps(outside of above) that no longer impacted my life negatively. It's a game changer. Once that all settled down, I was abel to start tracking my periods and moods and for the first time in my life knew when something was "outside the norm" and could get things checked out as they came. The positive impact outweighs the negative by far in my opinion. Peace of mind and regular light periods is absolutely worth it for someone who's emotions and hormones and periods have always affected negatively (before jaydess I'd pms what felt like 3 out of 4 weeks, cramp so hard id pass out and bled through so many clothes)
