please help me i’m freaking out

I had my annual pap done thursday everything came back normal (no std’s or infections) now all of a sudden my vagina has been itchy so I thought I had an oncoming yeast infection .. well it still itches but now I have this type of discharge? does anyone know wtf is going on? my OB doesn’t open until monday morning so I can’t even call. i’m also on the bc pill so I know it’s not ovulation cm. my periods supposed to start tuesday but the itchiness is driving me crazy
