Raw skin like spot inside vagina and very itch

I went to go get tested for STDs and BV and they all came back negative but I did have 1-2 yeast infections cause of cottage like discharge. I have no more discharge but I feel like I scraped myself down there because it burns and just is very irriated. It does not burn when I pee but I am very scared because I do not know what it is and I have been itchy for like a month! Please help!

It is probably thrush.
