Possible Chemical pregnancy?

On the 18th May I got a faint positive pregnancy test. It was accompanied with severe hunger, nausea and a very bad motion sickness (that does make me think that I was really pregnant). The next day the test was negative and since then it has been 2 weeks and the test remains negative (I have to test every week due to my meds). The symptoms went away a few days after the positive test…in total I had them for a week. All that makes me think that I’ve had a chemical pregnancy. Ok but if that’s the case shouldn’t I get my period? Or have any form of bleeding? I’ve had 2 miscarriages before (farther along) and there was so much blood, while now not a drop. I’m seeing my obgyn soon, but wondering what you guys think.
