indent or positive?

Okay so I took this last night (please don't say it's void after 10 minutes because I just had a baby and the pregnancy tests second line didn't get darker until later on/the next day) and I thought I saw a line but it was so faint I thought it was my eyes playing tricks on me. So I looked again today after I took out my tampon & this is when I took this picture.

BUT, I also started bleeding today. It was VERY light. And not dark blood. (*TMI) I put in a tampon and after a few hours I took it out to check, there was barely any blood. I've been cramping but I don't feel like it's the usual "cramp a week before I start" cramps. Could I be pregnant?
