Positive or evap line?

I've taken a million test and i swear i see a line on them all an hubby doesn't. The line got darker as time went on but he could only see them after 15 mins. So should i just call them all evap lines. I'm 20 days late an unfortunately cant see a doctor as in the middle of moving states and dont have insurance at this time.

Pink one he say around 15 mins

White one same and blue line one he saw at 12 mins. I have more test some i can see lines others i dont so i don't understand.
