Is this a faint positive?

5 years ago, my husband and I had an incomplete molar pregnancy, which turned into persistent gestational trophoblastic disease. We have been very nervous about TTC, and I've been very emotional because I can't go through that again. A few days ago, I thought I was getting my period but now I'm thinking it may have been implantation bleeding. So I took a test. This is what I saw. Am I just seeing things? Yesterday would have been day 1 of what should have been my period.
