Only reason I say that is bc I had a one and had NO symptoms at all... He was just doing a check and told me I had a bad one.. I was so confused. The only symptom I had was milky discharge, but I had that my whole pregnancy so I couldn't ever tell if it was just discharge or something else. My mucus plug was definitely brown/bloody looking though.
I don't think it's a yeast infection. I haven't had any symptoms.
Mine was brown looking, dark red kinda.. I've never heard of it being white.. Could it possibly be a yeast infection? Maybe someone else can give you more info to help!
