Ovulation Test Question

Olivia

Hi all !

This is my first time using ovulation tests and my first month TTC . I started testing Saturday and had no test line appear , Sunday had a very faint line appear , then Monday had a more pronounced line (see pic) . So I figured today (Tuesday) It would for sure be darker or as dark as the control line but it was even lighter than yesterday (much like it was on Sunday) ...does this mean I didn’t ovulate ? My periods are pretty regular every month .
