Pregnancy Info HOME

I'm 13 days late on my period and its been normal since my miscarriage in May. Now I noticed that I missed it so the Dr. sent me for a blood test to check my HCG level and it came back less than 2 but that was last week. I'm still late and feel really weird similar to how I felt before but more of a stretching in my lower abdomen. All the home preg tests come back neg. Has this ever happened to anyone and been pregnant?
