confused...please help me understand

S
I don't have a picture just a time line. I've been using clear blue digital opks and I test every day at noon and 10 pm. The tests I use give you either a circle or a smiley. Yesterday both tests were a circle. Today the test at noon was a smiley then at 10pm it was just a circle.

Does this mean I missed my ovulation?

I should also point out that my husband and I did the baby dance last night, roughly 12hours before I got the smiley.

I really hope I didn't miss my window.
