possible ovulation?

Ashton
Stimulation phase of fertility, 50mg of clomid.
On day 16 follicles were at 13 and progesterone was 0.3, I was told that I did not ovulate and that would not ovulate it was too late this cycle. Today is day 18 and I've had an increased of sticky mucus, could this be ovulation? Or some fluke? I don't have any conditions that would cause that.
