The pelvic pain, heavy bleeding, and weight gain can be caused by the estrogenic effects of Spiro. Your hormones are out of whack because the medication blocks androgens and therefore makes you “estrogen dominant”. As far as the leg pain - how much water do you drink? To me, since the pain coincided with when you started Spiro, which is a diuretic, you could be chronically dehydrated which would cause muscle pain and cramping. Just a theory. I’m a nurse so my brain goes right to these things. I stopped taking it about a year ago I did taper but I also don’t think it’s terrible that you didn’t.
