Questioning everything! Did I even ovulate?

I felt pretty confident with my cross hairs when they showed up given my positive opk....maybe even put O as 2 days after at the latest. But then my temps have dropped and continued to be low really early on. Now I'm questioning if I even ovulated. AF is now 2-4 days late (depending on which O day you say). All BFN which I'm not surprised by given my low temps. I'm not sure if I'm waiting for AF or if that's not going to happen since I didn't O. This is our 1st cycle after AF returned after a natural M/C at 8 weeks on July 8th so I'm anxious to move on to the next phase in our lives.
