Evap or Postive Test?

so today April 27th, was supposed to be the 1st day of my Period,and still nothing, i have been having headaches,and felt nauseous the other day, lost my appetite a little and seem to be very sleepy. i took this test today because my son who is 1yr. old has been very attached to his dad and not wanting anything to do with me. and also lo

because my mom kept on insisiting that iam Pregnant, so i waited for a result and it seemed negative ag 1st so i threw it away, my friend asked to see my test about 2 min. after i threw away my test and to my suprise o see a faint blue line. could it be an Evap. Line or a Postive line?
