I think I might be pregnant

I have missed my period by 11 days, about a week ago I had brown spotting, and I haven’t had much of a appetite. My last pregnancy resulted in a miscarriage, and my D & C was on Aug 15th. In September my OBGYN checked my hormone levels and they were down to 0. The first day of my last period was Sep 18th. I had a blood test done today and the results came back as “<2” which is considered negative. It’s been 2 weeks since the “deed” and I’m curious if this is normal levels for 2 weeks pregnant and if it could rise to a positive level. After the miscarriage, seeing the “2”/negative broke my heart and crushed my hopes.
