Cups and yeast infections

Soo I've taken to checking to see where my cervix is throughout my cycle but yesterday I noticed some unusual white stuff? Not a lot, if I hadn't been messing around up there I'd never have known because there's no itching or smell or anything like that. Can you get a yeast infection without the other symptoms and if that's what it is can a cup cause/contribute to it? I really don't want to have to go back to pads a week from now... sigh.
