I had a D&C on November 6th with very little spotting for a couple days afterwards, and no other complications.. The higher the HCG level is, the longer it will take for the woman’s levels of HCG to become normalized again. If the woman has HCG levels at 56,500 mlU/mL, then it may take weeks for her body to restore the balance to normal after a miscarriage has occurred.. Most clinics start testing beta HCG levels about 14 - 16 days after egg collection; and repeat the test every 48-72 hours. As the embryo grows rapidly, HCG levels normally double every 2 to 3 days. Thus, one reliable sign of a healthy pregnancy is the fact that the HCG levels are increasing rapidly, and often doctors will measure serial beta HCG levels 3 days apart in order to determine the viability of the pregnancy. A rising HCG level is reassuring. Typically, in a healthy singleton .
