What is cervical mucous and how is it measured?
Cervical mucous (or fluid) is the liquid that is produced by the cervix. The viscosity of this fluid changes as ovulation approaches. At the beginning of your cycle and after ovulation (non-fertile days), the cervical mucous is dry or sticky. As you approach ovulation, the mucous becomes creamy, then watery, and finally like eggwhites. “Creamy” cervical mucous may be white, yellow or beige and feels like lotion. When the cervical mucous is clear and watery, you’re most likely fertile and when it can be stretched several inches between your fingers, this indicates your most fertile days.
