Could I be pregnant!

I have been having some mild cramping and discharge yesterday it turned into snot like discharge (sorry for the TMI). Saturday I took a test and thought maybe it was positive (first picture) I saw a start of a line! And so did my friend!! Then like an hour later I went to show my husband and it looked like this! (Second picture). Is this an evap line now and it was negative or can it be positive and still give evap lines! I'm not sure if I should still call for a blood test?? Please help me out girls! You are all so sweet!
