Can you Ovulate late?

Evening ladies, I am just wondering about my chart. As you can see, I haven't started my period yet. I've taken pregnancy test around 1-3 days late, 2 looked slightly positive but one of them faded after I read the test. I took more but all said negative. I've never been this late (beside having 2 pregnancies) before. I know stress can mess it up, but I still have never been this late. So my question is, could it be possible that I ovulated later than what my tracker says? I'm planning on getting another test, but I want your answers! Every now and then I feel cramps, but still no period. Thank you!
