birth control
"I have been on this birth control for about 4 months and this is the best month in the four years I've been on birth control. I have extremely HORRIBLE periods anything you think of has happened in my experiences with the several others, if your symptoms start out worse or don't clear right away try and stick it out so your body can get used to it.  Periods went from 14 days to 4 days...I'm loving it!"
