Have you ever googled the site "My Beautiful Cervix". If you haven't, go look because they have all sorts of pictures that might give you an idea about cervical mucus. I had a look recently and they have added some early pregnancy photos now as well.

Generally, after ovulation my CM was like creamy with small chunky bits in it. It was white and increased in the week after ovulation. I didn't notice anything different during this time than when I wasn't pregnant though.
