Anovulatory cycle on Clomid?

Anyone experience this? Based on my bbt, I think I didn't ovulate. I took opk and had two smiley faces on CD 14&15 with empty circle on CD16 with cb easy read. It's now CD18 and temps are still low with no crosshairs given on ff. Wondering if I feared up but didn't happen...
