Then it's most likely just your regular discharge. Like I said it's very normal due to all the hormone changes your body is going through right now. I went through the same thing. You can always call your dr and ask if that makes you feel more at ease.

It could be another bacterial infection. They are very common during pregnancy due to the increase in hormones down there. Are you having any other side effects like itchyness or irritation?
