Anyone had this? This wasn't there yesterday

Lib

So I am 8 weeks PP, went to do my perineum massage that I was told to do at my first gyne appointment yesterday.

I was having a look whilst applying local anesthetic in the area needed and I have notice that it's turning black around the outside and dark Grey on the inside. Kinda like mold but I know my vagina is not moldy 🤣🤣🤣

This wasn't there yesterday and I'm worried I may have an infection as there is a bit more pain down there😭
