Help??

How accurate were first response for you ladies. I’ve had 7 faint lines on first response but negatives on other brands of tests. I am 14 days late and terrified to test now. I have an appointment on Friday but I got more tests sitting in the bathroom waiting. I’m so worried I have NEVER been this late on my period. Me and my hubby have been trying for over a year and I’m just curious on what you ladies think about frer I’ll post pictures of my first response and then one of a blue dye I took.
