Hormonal coil (IUS)  

Today I finally had my Mirena coil removed. The insertion and removal went smoothly and were painless. I had the coil for 10 months. During the first 6 weeks, I experienced continuous bleeding. After that, my periods became more regular but were very long up to 10 days and lighter than usual. After a period ended, I had another one a week later for only 3 days, and then the cycle repeated exactly every 28 days. I also had persistent discharge, infections, and cysts, and I even had to have a biopsy due to white spots on my cervix caused by the Mirena. Today, having it removed, I felt immediate relief. I was prescribed desogestrel tablets, so hopefully it will be better, although the pill doesn’t have very good reviews either.

I liked that it was minimal effort once inserted. My periods were far lighter and less frequently occurring. Because of the thickening of vaginal fluids being part of the mechanism; I found I because much more prone to UTIs after sex and also had lower sexual drive. I came off the Mirena because I wanted to track my cycle accurately to see if my hormones and cycle were affecting/triggering my seizures (I have drug resistant epilepsy). When I came off the Mirena I found I was less anxious over the months following swapping to the copper coil I.e. non hormonal. This had not been a concern of mine when on it.

The mirena coil did effectively reduce menstrual bleeding and prevent pregnancy. Due to thickening vaginal discharge I found I was more prone to thrush and also that this had an impact on arousal. I was an advocate for the hormonal coil until I changed to a non hormonal birth control and found that this had elevated my anxiety certain times in my cycle. I am epileptic without seizure control and this was my reason for coming off hormonal methods. Female hormones can trigger seizures in women with refractory epilepsy!
