We had sex on Sunday before I was due to put my
nuvaring in that day and all was normal. Sunday night, I inserted my
nuvaring and starting monday I have had the worst vagina odor ever. I smelled it Monday, washed it and went on my way but it doesn't go away. It is not a fishy smell, it is a foul rotten smell. My boyfriend and I were having sex last night and he smelled it and asked me about it.
