Yeast infection?? TMI

I’m a virgin but lately my discharge has been showing like this while it’s usually just white/clear and very liquidy.. it’s coming out clumpy/chunky and it has a bit of a foul smell.. sometimes its white too, help? i don’t masturbate either so if its a yeast infection idk how i caught it? taking these pictures i didn’t even insert my fingers i just slid them across my vagina :/
