Hi! I was just at my OBGYN yesterday for the exact same thing.
I was noticing some thick whitish/yellowish discharge, but didn't have the foul odor, itching or burning that are the classic yeast symptoms. But because I had never really experiened that typed of discharge, I thought I'd have it checked out and it turns out that it is in fact a yeast infection! I was prescribed 1 diflucan pill and was told it should be gone in a few days. Im 34 years old and this is the first yeast infection I've ever had...the Dr. was surprised because it's very common.
So, I suggest you make and appointment also and get it checked out....before it gets worse! You'll feel better too knowing it's been diagnosed and is being treated.
Good luck!
Thank You, I got into my doc and was also put on Diflucan!
