I am on the nuvaring and keep it in for 4 weeks at a time sometimes to skip a period (doctor said it's fine).This was one of those times, but I forgot to replace it and it was in for 32 days. On Saturday, I had sex where I thought he put a condom on but I guess he didn't (I know, I won't be seeing him again). I put in a new ring the next morning and took a plan b at 36 hours after. I am very paranoid about pregnancy and wanted to know if I need to be worried?
