abnormal uterine bleeding
"I bled for 7 weeks out of 2.5 months on Previfem. I also gained 7 pounds. I'd lose half of it during the placebo week, but it came back when I started the active pills again. 

I threw out my 3rd pack halfway through the active pills. It's been 4 days, and I'm 0.3 pounds short of my old, happy weight. Granted, it was probably just water weight, but my self esteem really is affected by my weight."
