Tweak picture?

Lisa
So i am now 6 days late on my period woke up with a stretching pain in my lower stomach and uterus not painful I just never experience that before it went away but I've been taking pregnancy test the past few days can someone tweak these for me I swear I see something everytime but then I'm like no I'm crazy 
In this picture the bottom test was taken this morning it's the most recent and the one above it was taken yesterday night... The rest are from earlier this week
