Will your hcg level decrease after the first day of a miscarraige?

Yes, after a miscarriage, hCG (human chorionic gonadotropin) levels typically begin to decrease. The decline may not be immediate, but it generally starts within a few days following the loss of pregnancy. The rate of decrease can vary among individuals, depending on how far along the pregnancy was and other factors. It's important to follow up with a healthcare provider for monitoring hCG levels and to ensure complete resolution.
