Sorry my phone must have deleted the last bit by accident, probably didnt explain it well Anyway I'll try again ... I started miscarrying 25 days ago .. Went for a scan then hgc bloods every 48 hours, last week my blood hgc levels were at 22 so she told me to wait u until tommorow and then take a hpt to see the results but just looked on the box and it said that they detected levels from 25 so if my levels were 22 it would have been negative then anyway wouldn't it! Or Are bloods different from urine? Thanks
