abnormal uterine bleeding
"I've been on Previfem for 3 months and I am still experiencing breakthrough bleeding that lasts until my withdrawal bleed. I take the pill at 6:15 every morning, and have never been off by more than 15 min. The only positives are that my breakthrough bleeding occurs like clockwork (after 12 active pills) and it made my skin better. But the bleeding itself drains the life out of me and makes me really depressed. 

I gained 7 pounds on the pill, but I think I had a hormone imbalance that made me lose weight before that. I had lost 10 pounds while eating everything in sight before that, and I had a period that faded into light spotting but would not stop for almost 2 months (only stopped because of the pill). 

I am switching pills next month."
