I was always on the Nuva ring but after my doc said it could be responsible for my terrible cystic acne, I switched to Yaz. Since I switched, I've had like 5 cavities (never had cavities before in my life) and I'll be getting my second hip surgery soon. I also fractured a rip just from coughing.  I'm just wondering if maybe the BC is to blame. Has anybody experienced anything similar?
