No back biting. Simply ignore nohard's suggestions regarding "homeremedies". He often suffers from "foot in mouth"disease and lacks common sense. One would suggest sticking garlic cloves up your vagina when pregnant might not be the smartest suggestion in terms of curing what might be a yeast infection.
It does sound a bit like a yeast infection (one is often prone to these while pregnant) although (I'm assuming) you are still waiting for the results of the blood work. Again, before you consider any other over the counter treatments for such things as a yeast infection, check with your OBGYN to make sure these are safe to use while pregnant.
