"This is honestly the worst birth control I've ever been on. I've been on several types and have never experienced acne like I did on Nora be. I stayed on it for 9 months, hoping it would get better but it didn't. It caused me to have painful cystic acne all over my face, the worst was by my mouth and chin. I had such bad cramps during my period that I was in tears. I just changed birth controls and these symptoms have gone away completely. I don't know why I had such a bad effect from it, but please keep in mind you don't have to suffer for months like I did."
