Norethindrone
"I am a healthy, active, college student, and I have experienced no negative side effects from this pill. I was scared to start it because so many other users gave it bad reviews, but I've been on it for 3 months and I've had no bad side effects at all. I'm also not pregnant so the pill seems to be working correctly. Micronor hasn't changed my moods or made me gain weight. The only noticeable change has been my breast size. Within the first month of taking Micronor, my bra size increased from a C to a D. I use condoms with Micronor to be extra safe, since it is not quite as effective at preventing pregnancy as other birth control pills."
