I am really uncomfortable. I am 33 weeks pregnant and I think I have a yeast infection. It itches, burns, and it is really, really uncomfortable. (Those are my only symptoms). I've never had a yeast infection before so I have no idea what I'm dealing with. I have an appointment with my OB next Thursday, but am debating whether or not to call him regarding this issue. I can't go tomorrow (as I have a lovely root canal scheduled). There's nothing for yeast infections on my approved sheet of medications from the doctor.
