I took a test last night. Positive or not?

I took this test last night and I thought I saw a very faint positive. (First and second pic) I know we aren't supposed to look at the test more than 10 minutes afterwards, but I looked at it again this morning, and the line was a tiny bit darker. (Second and third pic) Could this be my rainbow baby?
