birth control
"I feel like, based on all these reviews you either love it or you hate it. This works wonders for me. The first inactive week, the first period o had on it was HORRIBLE. But after that as my body adjust it really helped. Also I know it's terrible but when I was younger I had unprotected sex and I never worried because I always get my period on the 3rd-4th day of the inactive. Been on them for about three years now, would recommend if you have very little medical history to worry about."
