Yeast Infection? How do you tell if you have one?

I've never had a yeast infection before but someone told me that my symptoms describe a yeast infection. I have a thick white discharges, but it doesnt smell bad or anything and before the discharge appeared it was really itchy down there. Is that a yeast infetcion?

Go to Walgreen's or Eckerd and get Monostat cream..I had one once and it was SO itchy!!!! You can use ice for the itching and the discharge was white cottage-cheese looking no bad ordor..if you're not sure go see your doctor..remember to wipe front to back!(that's what he's gonna tell you)

you have to go to a doctor, Yahoo Answers cannot tell you if you have a yeast infection!
feels like an intense itching, burning sensation, localized in your vagina and vulva. this itching is not always present, but can get really bad, so bad you can hardly walk, let alone ride your bike to the pharmacy or doctor to get it treated.

looks like clumpy nasty white stuff. most medical descriptions compare the discharge to ricotta cheese, but it can range from thick and not clumpy to faintly yellow to thin and clear.

smells like bread or beer. in fact, it smells pretty much exactly like yeast, although the yeast used in brewing and baking is an entirely different species (Saccharomyces cerevisiae). no bacteria could smell like that, so it's a great diagnostic.
sounds like it.
Sounds like a yeast infection but I would go to the doctor and find out for sure.
