faint line? please help!

I am new to all of this but my husband and I are trying for baby #1.  I also sent a picture of the test thinking maybe the brand name matters. Today was the day my period was supposed to start and impatient me tested a few times prior and they were all negative. 
I've read about Evap lines, is there a way to see if that's what this could be? Sorry for the million questions, but we are so hopeful! Any advice or help would be appreciated!
