I'm 20, no kids, active, and have been taking orthotricyclen (a low dose pill) for about a year and a half. I want to switch to an IUD, but I'm not sure if Mirena or Paraguard would work better for me. Even before starting BC, my periods were usually light with no cramping, and I've never struggled with acne or anything like that, so I'd like to take the no hormone route. I've also heard that Mirena causes weight gain and low sex drive, which further turns me off to it. So my question is, has anyone switched from a low dose oral BC to Mirena and still experienced those side effects? Or am I better off with Paraguard and suffering the heavier periods?
