Cervical Mucus Before (after ovulation) Period? - does cervical mucus change just before your period

I played here and see lots of people are wondering what type of CM is to begin before their period. Some say lotiony, creamy, and some say no. What is it? I tried Google, and not its application, and a clear answer.

What type of cervical mucus that is supposed to have before menstruation?
I would say that anyone who was not on contraception or medicine, and I know that CM changes. I realized that a part for a while when I was on the pill.
Sorry, I've never paid much attention to my own body. It made me curious when I saw so many questions on this topic.
