Miscarriage?? Still getting + hpt

Hey guys! So I took 7 hpt in a week and they were all positive. Including the digital. About a week later I started to bleed. I bled for 1.5 days. I went in and they said my blood hgc levels were less than 1. So I had miscarried. It has been 2 weeks and I'm still getting positive hpt. If my blood was less than 1, 2 weeks ago how can that be? I understand it takes awhile to leave your body but I would have been around 4 weeks when I went in and If it was that low than how are the hpt still coming up positive? I also still feel pregnant? Any advice. Will be checking in with my obgyn soon. I was also diagnosed with a bleeding ovarian cyst at the same time( found via ultrasound)
