Nuvaring Issues

Ainsley
Hi,
This is my first month on nuvaring. While I was on it, I had no symptoms, no issues, it was perfect! I'm "off" for a week to have my period, but I've been nauseous and having hot flashes for three days. Is this normal? Should I be worried? Can I fix it? Not even strong nausea medicine is making the queasiness go away.
