Evap??

I have a few questions... so yesterday afternoon I decided to take a test (I take one every month just in case) so after a few minutes nothing was showing so I took it as a negative put it in my purse to throw it awand went on with my day ... I went back because I remembered about it and was curious to see if something had popped up and sure enough two lines... could this be wrong? Evap lines??? Don’t get me wrong a baby is a blessing but it would be in the worse possible moment of my life ... re testing tomorrow..but I’d like to know some opinions on this..
