Help!!!

I had unprotected sex 2 times with a guy & the first time i got a yeast infection. the second time nothing happened at first but i was super itchy down there. today i got out the shower & as i was drying myself i noticed that there was some white stuff on my clit. I got some of it off but then i used a flash light to see what was going on & i saw what seem to be red spots on my clit. I have an appointment with at a sex clinic on friday, but it’s currently sunday and i am freaking out. does anyone know what this is???
