Cm and cp help

Stacy • Married 9-6-14!! Have an amazing 7 year old boy and a 2.5 year old girl. Due with baby 3 6/24/19
Can someone please tell me or give me a link to what the different types of cm mean as well as the different positions of my cervix and what I should be looking for with both to show ovulation. Gonna try monitoring both of these this month and see if that works. Thanks!!
