Not ovulating?

What is going on this month? I know my charting isn’t perfect this month since I couldn’t temp 3 days, but what do you think is going on? I got my peak readings later this month than normal, but was thinking I’d ovulate yesterday after a peak reading on a digital on CD17. My temp didn’t rise this morning though. My cycle is 29-31 days so this feels really late in my cycle. Starting to worry I won’t ovulate this cycle.
