Couple Questions 😅

Well first my situation . . The first day of my last period was January 11th. And in a few days I should be coming up on my SECOND missed period. But I've been testing since my last period and everything has been negative, so I just figured I skipped a cycle and ovulated late... I have been researching like crazy, and found something called the hook effect? So I diluted my urine this morning. And I think there was a faint line?

So if I retest tomorrow should I dilute my urine again? I'm caught between thinking I'm farther along or not far enough. Any advice ?
