Omg somebody help

Ok guys I was in the middle of foreplay.. and I noticed a horrible (fish like) smell.. I’m not saying my vagina smells like roses but Jesus it’s never smelled like this.. it was the absolute most embarrassing thing I have ever gone through in my life. Somebody tell me what that could mean? I take 2 showers a day .. I keep myself clean!!! What could this be ?! 😫
