Yeast infection I think...HELP

I didn't want to post a picture because it looks gross but yesterday my vagina was having this itchy feeling but I didn't pay it any attention (b/c I thought it came from shaving) so eventually I had to pee and when I wiped it started burning slightly I got scared and I knew at that point I had to check to see what it was. I put my mirrors on top of my bed and shined a flashlight on my vagina (there's nothing wrong with the outside btw) and when I pulled the "lips" back exposing the inside of my vagina it had a white clumpy coating I've never had a yeast infection before is that what I have? If you want to see a pic I will send I just want to gross you guys out😩😞
