Can anyone help me??

I’ve been taking ovulation tests everyday. This morning I took one and the line was FINALLY starting to get darker than the ones I took before that. I just took one JUST NOW, and there’s only the control line... I took 2 different kinds of tests, and still, ONLY the control line.

What does this mean?? Should I be worried that I won’t ovulate?? I’m so sad and scared cause Nov 2, my fiancée and I are purchasing 2 vials for us to have a baby....

Can ANYONE please help me?? 😭😭😭

EDIT***

I went to bed about 6am and took that one test that the lines were darker, about 3am. Before I went to bed, I drank a ton of water. Could this affect the test that I just took??
