Could I be pregnant?

Had my last af at the very end of March or very beginning of April can't remember the exact date but I assumed I would get it between May 2 to the latest May 6 this cycle as I am usually on time. Well I decided to take a test on Monday but it was in the evening and I got this very faint second line posted in the pics below. I haven't tested again yet because I'm scared of it being negative as I have been trying for a little over 3 years now for my baby #2. Please let me know if you can see the faint line as well and I'm not just getting my hopes up for nothing again. I am going to retest either tomorrow or Saturday but it sure would be nice to know that I'm not just seeing things.
