Is anybody else on Clomid?

My ovulation has been thrown off for that past 3 cycles! Cd 18 and I still haven't ovulated! I had a follicle test with an ultrasound last Wednesday and they found quite a few mature follicles and said that I would be ovulating soon.  I always ovulate on cd 16.  Yesterday I had EWCM (tmi sorry) and today I started cramping a little but no positive opk 😠.  These eggs have got to be ginormous by now!  Anyone in the same boat?
