No period, & BFNs. Heeellllllppppppp!!!!!!

I haven't had a period since January 10th 2017. I've taken 4 hpts over the last week and they seem to be negative in the 10 minutes. But when I lool at them a couple hours later. I see a test "line" that has color and is just as thick as the control line. Is it possible I could still be pregnant? Or are they just evaps? Heeellllpppppp!! Pics to show what I mean. 3 min, 10 min, & several hours later
