Indents?

I thought first response was A1 till I read a lot of bad reviews about indents now I’m so scared to believe I’m pregnant if it’s an indent. I bought a pack of three, and took one last month came back negative the these two (top one is today, bottom is yesterday).. if I got a negative off one does it make these two reliable??

.. I’m 5 days till period, 28 day cycle & fr digital ovulation test said I didn’t ovulate (first time using) could I have ovulated and it just didn’t pick it up??
