Decrease: HCG levels should decline rapidly after a miscarriage. There are a couple of reasons for the increase, (1) you are pregnant again, (2) if that is not the case, please consult your doctor to rule out retained products of conception that may still be growing and need to be addressed.

See your Doc: If your HCG levels are still rising, you need to be re-evaluated by an Ob/Gyn. After a miscarriage, the levels should continue to drop to zero. Rising HCG levels after a miscarriage can indicate something serious such as Choriocarcinoma. Its also possible that the initial diagnosis of a miscarriage was incorrect. Don't wait to have it checked out. Best wishes!

A 36-year-old member asked:

If I have low hCG levels, does that mean I am going to have a miscarriage?

No: Hcg alone cannot tell one they are going to miscarry. In early pregnancy the HCG should double every 2-3 days. If it is falling, or is not rising substantially over time, it is likely that there is a problem with the pregnancy (impending or current miscarriage, ectopic pregnancy). Once there is a visible pregnancy on ultrasound, hcgs have little value, and the ultrasound is more meaningful.

Is a miscarriage imminent if my hCG is not doubling?

No: Serum HCG levels are expected to rise by 2/3 (not double) every 48 hours or so in the first 8 weeks of pregnancy. However all doctors have had a patient where the HCG rose , just not by that much and ended up in a normal pregnancy. An HCG level that doesn't rise at all or falls is much more concerning for miscarriage.

Depends: It depends on how high the level was to begin with. If the miscarriage is complete, the level will go down quite rapidly and generally should be negative in 10-14 days.
