Does mirena coil cause cystitis?

I loved every second of using the Mirena IUS. My periods stopped, I didn't experience any symptoms of PMS and felt generally way more level (and it was a chaotic time when I was using it!) The only reason I took it out was because my time was up with it and got it replaced with the Levosert, which I liked a little less - I'll leave a separate review for that one.

did not work for me all of the sudden started to have panic attacks

I got an IUS inserted after 7 years on the combined pill. I did a lot of research, and it seemed like the safest option for me, with a family who has cancer/blood clot history. Insertion was uncomfortable but not too painful. However, I then bled for the first 6 months non stop. It eventually subsided, but then roughly each month I got THE WORST one-sided stomach pains imaginable, followed by some spotting. I put up with this for a year to see if it would stop, and it didn't. I went to my local Sexual Health Clinic recently, who informed me that I was likely experiencing ovarian cysts, which could be triggered by the coil. I therefore decided to get the coil removed and try something else.
