Cervical Mucus??

Kk

Okay quick question!! Do you all have different CM/discharge in your underwear all the time and that's how you check it? Is there supposed to be stuff in your underwear at every stage of your cycle? Are you supposed to have discharge in your underwear all the time? Or do you physically check it with your fingers? I'm new to this so sorry and also that was more than one question so also sorry for that :)
