Hormonal coil (IUS) and irregular periods

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.

I had the worst time on Mirena. I had a bad experience from day one at insertion - I found the whole experience so much more painful than I imagined that it would be - no one really prepares you for this. From the first day I started experiencing cramps and everyone said that they would ease up within no time however they did not. Month after month I experienced endless painful cramps and times where I would be doubled over in two on dates with my boyfriend - never have I had anything like that. As a girl, we very much always shut up and put up and I always felt like I could just push through it but there were times when it was really bad and I almost got it out, but you’d forget about it the next day as it’s such a good feeling to not have to Take a pill etc and it is very convenient. But it’s also crazy I actually had it in for as long as I did. I have never really had that bad periods and my bleeding was longer, the cramping much more intense and honestly just a whole lot worse than it was when I was off it. I didn’t really notice anything kind of sexually or from a weight or ski. perspective but I know that the cramping and the bleeding was enough for me to never touch this thing again. The Doctors kept telling me to hold out and just wait to see if it would change and it just never did. I would really recommend if you are having these symptoms any time past two months they are not going to get better and you’ll just continue to suffer. At the eight month mark I went and got it out and honestly it was the best thing I ever did. As soon as it was out, I felt like I could actually breathe again and havent suffered another cramp like it ever since (thank god!). I have gone back onto the mini pill now which I’m much more happy with - it does have some side-effects but nothing like that cramping!
