My DS is now 9 weeks old and I had the Mirena fitted last week after hearing that it can really help with heavy periods, I have PCOS, struggle with lack of periods and weight gain (previously on Metformin for 4 years) and extremely heavy and painful periods for which I take Feminax + Mefenamic Acid. After the fitting my first period since the birth kicked in and on top of it being just as heavy and painful as I remember it, it has lasted much, much longer than before and is still now over!! I am really worried as I have now read that Mirena can cause ovarian cysts, weight gain and heavy periods and am wondering if I have made a SERIOUS mistake???? i'm now thinking that I would much rather have monthly periods and the pain
than not have one and be wondering if my PCOS has returned? I am not yet sure if I want to have more children but would love to keep my options open!! anyone out there have any experince with PCOS and Mirena?
