Does it itch? Could it now be fungal due to ph changes in the vagina, yeast or just fungal? Okay, I have to ask. Prenatal care is important. Why aren't you doing that? Are you going to start? As you get closer to your due date, it is best to work with your doctor. Who prescribed the metronidazole? You can visit them again to get the current discharge swabbed. However, if it is just thicker than usual, doesn't smell or itch, it is not bad to wait to see if it clears up either. Anyway, I hope you can start working with a doctor on a regular basis soon hon.
