birth control
"Great BC. Initially I gained about 5 pounds but that's probably the case with every BC and you can work to keep it off. Didn't change my mood or my sex drive, and periods have been much more bearable. Only thing is--if you mess up the pack (i.e., miss a pill, etc.) your period can last start early and last very long. Try to keep a consistent schedule with this pill. Oh, and I've never been pregnant either."
