Yeast infection or pregnancy thing?

So I’m in the bath and this weird discharge came out of me, is it a yeast infection or like some kind of pregnancy thing? I’m FTM and 33 weeks so I don’t really know what’s normal and what’s not 😅. If it is a yeast infection how do I treat it? I don’t have any itching, burning, or bad smells I wouldn’t know if it’s a yeast infection as I’ve never had one before.
