I have been on nuvaring for a year and a half. I took out my nuvaring on Friday 7.1 and my period came on a Tuesday 7.5. I was suppose to reinsert the nuvaring on Friday 7.8 but, I wasn't able to get it. I had unprotected sex on Saturday 7.9 but took a plan b Monday 7.11. Reinserted nuvaring on Wednesday 7.13 but had unprotected sex on Saturday 7.16 1am. Should I take another plan b?
