Is it possible to not ovulate?

I usually ovulate on the 14th day of my cycle. I also tend to have a temperature spike around that time and it stays high until I start my period which is pretty much always day 24 of my cycle. This month I haven’t gotten a positive OPK and I also haven’t had a temperature spike. It’s it possible I just didn’t ovulate this month? It is now day 19 of my cycle.
