TTC after D&C

Michelle

How long does it take for HCG levels to get back to normal after a D&C? 

D&C was 3 weeks ago today. I was 10 weeks but the baby was 6 weeks. When I first found out the baby had to heartbeat at my 8 week u/s she was measuring 6-2. They said she was shrinking in size. Since she went down 2 days in a week.

I had very light pink spotting yesterday and for the hexk of it I took a pregnancy test. It was very light positive. Left over HCG from miscarriage?
