Am I pregnant? Very faint line... maybe? Or am I just silly?

Hello!
I feel so so silly posting this. I took a pregnancy test as glow said I should. So I did. I went to throw it away but then though I saw a faint line. It's a very cheap test so I'm sure it's just wishful thinking as I've been trying for 1 1/2 years but I thought I would just ask. I took another test half an hour later and another one half an hour after that, and can't see anything on the other tests. I've photographed all three tests. The one on the top is the one I first took and the one on the bottom is the one I last took. I'm going to the doctors tomorrow and was wondering what you thought. If you think it might be something, I will mention it. If not I won't as I don't want to waste her time and appear foolish. Thank you so much xXx
