I started on orthocyclen in December. So far yes it's prevented pregnancy but it extended my period I went from 3-5 to 6-7 now currently on 11 days. I keep breaking out and have been dealing with my hair falling out in globs. I told my doctor about it she is saying just stay on and give it 6 months. I'm taking myself off today. Wondering if anyone else has had problems with this birth control?
