Mirena coil and spotting

I used an Mirena coil over 12 years, having 3 inserted over that time. The first one was great, I was really pleased with it. Periods basically stopped and no real side effects. With the 2nd one there was sometimes period pain aches after sex but not always. However when it came to have it replaced nearly 6 years later it had moved and took some finding. At the time I just had the new one immediately put in but I was worried about it moving again and didn't relax so have had it taken out after only a year. As I am now 48 I do not know if things like my mood, no sex drive, random spotting, or anything else was linked to the Mirena or peri-menopause, so have not listed them as side effects for this (as more likely peri at this age)

Insertion was incredibly painful and had cramping for 3-4 days following. It's mostly been fine and no massive changes apart from excessive bloating and nausea. Since going on the coil I've been diagnosed with IBS which I didn't have symptoms for before so I wonder if it's linked. I had no periods for 5 months and now just really light or spotting for a few days.

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.
