vaginapagina | Non-hormonal birth control

I'm posting on behalf of a friend who's not a member of the community. Her problem:

"I can't take any form of birth control pills (I was on Nuva Ring) anymore because the hormones appear to make me dreadfully ill. Apparently I am one of the people at risk for strokes, seizures, etc. because HBC gives me migraines so severe that I have numb spells where I can't feel my hands, feet, or other body parts. I'm sexually active and I also have PCOS. My doctor doesn't recommend copper IUDs, and I've done some research and I agree with her."

Any suggestions, recommendations, or similar sories to share? Thanks, guys.
