birth control
"This birth control is great, except I missed a pill one day and doubled up the next day and I had my period for over a month! It's great compared to my last pill, which was marvalon, which caused me to have mental confusion, gain over 25 lbs! & caused me to have low iron. Now this pill I've lost 15lbs of the 25 lbs without diet or excercise and other then the one little mess up my mental confusion has mostly gone away!"
