OPK always negative ??

Ok I've been using OPK since January. When I use clearblue with the smiley faces , I never get the 4 peak days. It goes from flashing to steady face the next day. I decided to switch to first response digital that gives a Yes or No answer. I never get a positive and this month we have been BDing like crazy. Is this normal? Am I not ovulating?
