Yeast infection and first time pregnant

Well, I'm pretty sure I have a yeast infection. I have two separate doctors appointments next week (one with my primary on Tuesday, other with the OBGYN on Thursday), but until then, is there anything I can do that's safe? From what I've read YI's are pretty common during pregnancy but I'm still worried it will harm the baby in some way. I'm 6w 2d. I plan on calling the Dr. in the AM as well to see what they recommend (not sure if they're into the whole 'self-diagnosing' but I'm pretty sure that's what it is)
