Very faint positive, opinions?

Hailey
Right, I've missed one period that I was due last month and now I'm due my second period but it hasn't started; it's 5 days late now. So I did a test last night, I thought it was negative but it had a very faint line. I spotted it after the time frame so I assumed it was an Evap line but thought it would be best to do another test first thing this morning. This one had a faint line straight away, and although it is very faint it's defo stronger than the one from last nights test. Here's a picture, although it's not as obvious as it is in the flesh. Can someone help? What can I do? 
I can definitely see a faint line, it appeared straight away. No idea what to think! 
UPDATE!! 
Just to let anyone know who may be experiencing the same kind of thing with a very faint positive; I've tested again and i am pregnant, about 4 weeks along so it is REALLY early to even find out! Good news people!! Good luck to anyone else trying! X
