I'm really worried and looking for some guidance. If a miscarriage happens around the 4th week, what should the HCG levels typically look like at that point, and how do they change after a miscarriage? Also, I'm curious about what the HCG levels are when someone isn't pregnant. How long does it usually take for the HCG levels to return to normal after a miscarriage?

The normal hCG levels at 5 weeks LMP is 18 7,340 mIUml. The hCG level in your blood doubles every two to three days when you're pregnant. If your hCG doubling time is slower than expected, or if it decreases over time, this may be a sign of a miscarriage or an ectopic pregnancy. An hCG level of less than 5 mIUmL is considered negative for pregnancy, and anything above 25 mIUmL is considered positive for pregnancy. It can take a variable amount of time for hCG levels to come to normal after miscarriage but it usually comes to normal within 2 weeks after miscarriage.
