abnormal uterine bleeding
"Great experience so far while on this pill. First thing I noticed was my cramps had dulled down A LOT. When my period started, it was the lightest one I have EVER had! Completely manageable and lasted like 5 days (when my other ones while not on the pill were 6-7 days.) Hasn't lowered my sex drive (in fact it might have upped it now that I think about it), no acne problems, etc. And the great part is I get it for free!"
