Please help 😓

So I have been 19 days late to my period. Took tests and came negative. Can it be that I still haven’t ovulated? I did scan and blood test last month and I have no pcos or endometriosis. What can be other causes to period delay? I had sore breasts below abdomen pain 1 weeks ago. But now I don’t . I feel extra wet feels sometimes. I don’t know what’s happening with me 😓
