On CD 41??? No AF and Not pregnant

Newly TTC. I stopped taking the pill a few months ago in October. My first cycle after that was 33 days, then the second was 27 days. This month I am currently on CD 41. AF has not arrived and I took a Clearblue Digital Pregnancy Test this morning (FMU) and it read ‘Not Pregnant’. Is this cause for concern that I’m not ovulating? Should I just hang on & just wait for AF? Anyone else experience a long cycle like this within a few months of coming off the pill? Thanks for any input!
