has anyone used Dr. Billing's "Ovulation Method"? it just checks cervical mucus and not temp or anything else. i've read his book and looked at the online resources. BUT, i'm wondering about checking cervical mucus. the book says not to do an 'internal' exam. so, WHERE exactly do i check it? inside or outside the inner labia, maybe?? if anyone has taken a class in this method, can you tell me where you check?
thanks.
thanks.
