Yeast infection and light spotting

I've been spotting very lightly and light pink for almost 3 days. I'm pretty sure I have a yeast infection as there is -tmi- pieces of yeast when I wipe and record the spotting/cm and I'm itchy 😩 I do spot before af, however she's not due until the 20th. I know the only way to know is to wait and see what happens, but has any one had light pink spotting caused by a yeast infection before?
