Medroxyprogesterone
abnormal uterine bleeding
"My pms usually rendered me sicker than a dog with irritability, debilitating body pains,  and a ravenous appetite after the carnage. I started taking this stuff at 18 years old and had my first needle in the middle of the period despite my dad's distaste of messing around with horomones. the first year I had to deal with light spotting that gradually faded overtime.
