Maybe baby?

This was one minute after taking a test two weeks ago. That same day I started what I thought was my regular period, seemed to last just about as long and seem to be just about as heavy, by this point I would have only been about 2 weeks pregnant, then today, a little over a week after the end of my period, I took another test. Digital one this time, and it still says I'm pregnant. Is it possible that the hormone is still in my body after so long after a chemical pregnancy, or is it possible that I am still pregnant? I have no idea. I have a doctor appointment later this week to check it out, and I'm pretty sure it was a chemical pregnancy, but I just thought I'd come here and seek out some advice or insight.
