Need OPK advice please! Worried.

Rebecca • EDD 3-23-18 baby #3!
Does this look like I may have ovulated CD 10? That was my darkest opk at 9pm. Last month I got my + on CD 11 and today is CD 13. I don't temp. I'm worried I may have missed my surge or I'm not going to ovulate. I have short cycles 24-27 days. CM has pretty much dried up but I can't believe I could've missed a surge in 12hrs overnight between testing.
