Ovulation is confusing me

Katie • Stay at home mommy as of 6/30/16!!!
So here's my question is it possible to ovulate and not notice change in your cervical mucus? last night and today I am experiencing cramping and I know ovulation is here or right around the corner. Yet when I go to the bathroom there is not much and if I wipe I don't see much. 
Obviously a big sign telling me that I am ovulating is the cramping that I have because I always get that when I ovulate and my calculator telling me ovulation is here.
