Hormonal coil (IUS) and body hair increase

I've had the hormonal mirena for 14 months now to reduce endometriosis symptoms. My periods have reduced in length (used to be 3 weeks) and happen irregularly and the pain has settled during these. I have however noticed continuous weight gain since I went on it, despite very little changing in my diet and exercise. I've always stayed at a very stable weight and now my breast have nearly doubled in size and my weight in general continues to creep up. I have tried upping my exercise with no improvement in my weight. I'm the heaviest I've ever been, except for pregnancy. It's a huge price to pay for a reduction in endo symptoms. It's very frustrating.

Kyleena was recommended with mr having Adenomyosis due to wrongly being given the copper coil before and bleeding for months on end. Kyleena had irregular periods to begin, the only sidr effect for the first 4 months were severe coldnesd/flu like symptoms the day before my period for all 4 months. As my periods stopped, my sex drive and mental health crashed. I'm on month 9 and awaiting removal.

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!
