PLEASE HELP!!!

Ok when I took the test it looked like a BFN yesterday evening but just a few mins ago I looked at it I seen this. Is this just an Evap line or what?? I have been so nauseous and tired and irritable. Idk if I'm pregnant or if I am catching a bug. Please help. Hubby and I have been ttc for 15 months. He is on clomid to help boost his fertility. Anyone's so had to take that and got positive results with it?
