What to expect coming off NuvaRing?

Haruko

I took out my nuvaring 6 days into a new pack. The reason being: aura migraines. hormonal birth control + aura migraines = big health risk. Monday, I have an appointment with my OB/GYN to switch methods (thinking copper IUD). what side effects can I expect? I am already cramping and it's only been a few hours since I've taken it out. I know I can expect some bleeding but I'm just curious if there's anything else.
