When do the hcg levels get out of your system after a mc? It's been almost 2 months since my mc and over a month since my d&c surgery.. I had a blood test a week or two ago and they said I still had hcg hormones in me. Two weeks before the blood test we got the ok to start trying again, which we did. I'm not sure if that's even possible but figured I would add that. I go in on the 31st for another blood test to see of my hormones are gone, continuing to go down or going up.
