Yeast infection??

Lately for the past couple of days I’ve been experiencing an odorless white discharge that’s not super thick but kinda like wet toilet paper if that makes sense. Around my vagina is also a little sore, not really itchy or anything but mainly sore. I’ve also felt small bumps on my lips as well. Do you think it’s a yeast infection?? I’ve honestly never had one so I really don’t know!

I’ve also started nursing school so I’ve been REALLY stressed about that and I’ve changed the style of my underwear recently to a bikini style cotton, but I don’t know if that would make that much of a change! I usually don’t sleep in underwear just a big shirt or really big pants.
