"i was put on the birth control because i had a very large fibroid that caused me to have a blood transfusion.  this pill saved my life until i was able to have surgery.  the only   negative thing i experienced was a little weight gain (no more than 10 lbs).  my periods went from extremely heavy lasting 7 days, to very light only lasting 2 and a half days, to staying completely off.  and for someone who was dangerously anemic, i&#039;ll take not having a period!"
