How long after chemical pregnancy does hCG drop?
The researchers reported there was a 35 to 50 percent reduction in hCG levels 2 days after, and a 66 to 87 percent reduction 7 days after the pregnancy resolved. This is a significant drop, but these numbers still mean that you could test positive on an HPT for a week to several weeks after a miscarriage.
