Advice please!

So I have been using clear blue advanced opk this month. This is my second month TTC. Last mont I had two days of blinking smiley faces and then on the third day I had a solid. This cycle I had two days of blinking smiley faces and then I went to a circle (no surge). Do you think I ovulated and missed it? Or that I didn't ovulate this month...?? I'm so confused! Last month I had a chemical pregnancy ... not sure if that has anything to do with it. Any advice would be helpful!
