abnormal uterine bleeding
"Before Mononessa I tried 4 different birth controls (can't remember the names) but all of them gave me bleeding constantly, it was horrible.  Finally I tried Mononessa. It's helped so much, my periods are much lighter, no more acne, and I didn't experience any weight gain like the other reviews I have read.  Also it is a lot cheaper. This pill is the one I've been needing."
