ok, I really need advice.

I've been taking tests since Tuesday and I can a really faint line but when I try to take pictures of it, it looks negative. I spotted a little on the 10th, so Monday. I had a positive opk the 1st of the month. Now that it's Friday I took another test and it came back like this? Should I just accept the fact that AF will be showing this month? I'm 12 DPO.... really any advice and a peace of mind.
