"great bc. initially i gained about 5 pounds but that&#039;s probably the case with every bc and you can work to keep it off. didn&#039;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&#039;ve never been pregnant either."
