Cervical Mucous Ball Cervical Mucous?

Cervical Mucous? - cervical mucous ball

I have a cycle of 28-30 days, I m currently on CD 21 and I ovulate on the basis of Fertility Monitor and tuberculosis. Now keep in mind a lot when aqueous cm thick. When the game begins to thin and watery, without stretching. But when I rub my fingers and enough time to dry if the things I rub my fingertips, continue to roll in the dry balls. What type of CM is the classification?
