may be your mucus plug. Some women get it and some dont. Its your body natual way of preparing for the birth of your baby. hope that helps
Normally i would say its probably just a yeast infection, but since you are so close term you should contact your OB to get advise on if its safe to use anti fungal creams or not. I am unsure if they are safe with the chance you may have some dialation of your cervex at the point..
