abnormal uterine bleeding
"I was put on this pill to help treat high  testosterone, I have PCOS. It should be noted I have uterine fibroids as well. I'm in the 2nd week of the pack. This is also the 2nd time in my life I've been prescribed this pill. And now both times it has caused extremely heavy bleeding, clotting & my uterus is contracting. This is not a normal "heavy period" bleeding. I've been to the ER for this, it's not something to dismiss. If you're having really heavy breakthrough bleeding &/or extreme mood swings please don't wait, call your doctor asap. This pill is just not made for some of us ladies!"
