Question about ovulation tests!!

Emily • My cute hubby is 25 and I am 22. We made a cute person named Thor born on June 29th!
So I took an ovulation tests around 11 this morning and there was a line that was more than faint but not yet positive. So I just figured I would ovulate tonight or tomorrow. Took one just now and the line was so faint that I could barely see it! Like, nearly nonexistent. Does that mean I already ovulated yesterday? This is my first time taking them so I'm not sure!
