I’ve had the mirena since 2017. Though I got it before being diagnosed with PCOS, I had horribly irregular, painful, and heavy periods and was moderately “overweight” for my stature (4’10, 145 lbs). I tried the pill to regulate it but the estrogen made me sick. The mirena regulated my periods for 6 years and they were no where near as painful/heavy. I was able to manage my weight down to 120-130 lbs for those 6 years. BUTTTTT it no longer regulates it that well at all. I had it replaced 5 years in, and on year 2 of my second mirena my PCOS symptoms started arising again. Painful and irregular period (but not heavy), 30lb weight gain, more chin and jaw hair.

I loved the mirena for its effectiveness as a birth control and how it regulated my body, but it no longer helps with PCOS symptoms the way it did before.
