Cervical Mucous Prior To Period Cervical Mucous?

Cervical Mucous? - cervical mucous prior to period

I've heard this all-inclusive and you will see your cervical mucus, but I do not understand how. Mucosa is happening in your underwear or do you know there every day (sorry, I'm very confused how it works), I wonder! Also can anyone tell me the different types of cervical mucus and what they mean for the tax?
