I'm grateful to see others have the same experience with the ring. I started it last month. I had told my doctor that oral BC made me sick. She recommended the ring since "it rarely has side effects". I had it in for 10 days and couldn't take it anymore. I was having hot flashes, headaches daily with nausea and bouts of dizziness. I was also moody and extremely fatigued. I call the office last week and doctor wasn't in, but the nurse said to take it out. Doctor called yesterday and said she felt it was just the flu going around and wanted me to try it again. So I put a new one in yesterday and 2 hours later started with headache. I've been tired and today I'm already having hot flashes. I had my period 6/25, and 7/9 (since I took the ring out). It sucks because I don't think I can handle the ring and when I take it out, I'll have another period. I feel awful on it and my friends say it's "in your head" but reading these validate my symptoms.
