Mirena coil and migraine with aura

Have only had the coil for 2 months (although feels like much longer) so will give it a bit more of a chance, I also acknowledge that everyone reacts differently and my side effects seem to be less common, however in my experience and at this point in time, the negative side effects FAR outweigh the positives. My GP talked me into trying Mirena for managing my PCOS and the excruciating pain I would experience on occasion from burst ovarian cysts, as well as the birth control aspect. I’ve gone from an abnormally long (but fairly painless) cycle to an even longer one, bleeding and in moderate-severe pain almost daily. If my stomach doesn’t hurt, my head will be, or both. I’m not joking when I say I look pregnant from abdominal swelling on top of it all.

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 to come off Mirena after about 8 months and paid to have it removed as the NHS were taking too long. My mood was through the floor, like really bad PMS but all of the time, I hated myself. This lifted almost immediately when it was removed. My periods were lighter but they were also really long, 12-14 days after normally being 4-6. Not much use as contraception if you're always on a period. The biggest side effect and reason for stopping though was heart palpitations. These are not listed on the side effects but a quick google will show you how common this is for women on mirena. They used to take my breath away when i was talking. As soon as I stopped, so did they so I have no doubt they were connected. A horrible experience and such a shame as I really was on the bottom of the list of options having tried most other things and I had really high hopes as this was working great for my sister.
