Positive or invalid

Ok ladies, so I’m 4 days late.. I was supposed to start on the 5th, but still haven’t had any sign of that happening.. i took a test Sunday evening, and it was negative.. but since I hadn’t had any sign of my lady friend I decided to test again today on my lunch break and I’m not sure if there was a faint line, but when I got home I got home i checked it again, and it looks like a positive, but I’m just not sure.. can anyone help and let me know if they see a faint line in the first 2 pics... my husband and I have been ttc for 3 1/2 years now, and this is the first time I’ve even thought i see a faint line..

This pic is from today..

From today also, but at a different angle...

Pic on left is the one from today a few hours after taking it, and pic on right is from Sunday.
