What Causes Thick Mucus Vaginal Discharge Along With Itching In Vagina?

Hi, the past couple days I have been feeling itchiness in my vaginal area, and when using the bathroom i noticed I had some beige discharge. Being curious I got a mirror and saw that I had thick, beige, odorless discharge build up in my vagina. I have never had an yeast infection, but I m wondering if thats what it could be.
