Cervix position & CM

What should I expect from my cervix and cm if I am pregnant? Is the soft high cervix full proof? What about the creamy white cm? Can’t tell if I’m cramping for my period or just feeling symptoms. I should get my period soon if I’m not pregnant: I have the creamy white Cm and a bit more of it than I normally do during this time. Also my cervix isn’t super high but it’s not low either. It’s not hard either. It’s our first time trying so I’m trying to figure it out :)
