What Is HCG?

HCG is also known as:  human chorionic gonadotropin.  HCG is produced during pregnancy and can be detected by a blood test 8-11 days after ovulation.  HCG maintains the corpus luteum which is responsible for progesterone production in early pregnancy.

What Are Normal Beta hCG Levels?

There’s a wide range for what is considered “normal” hCG levels during pregnancy.  One hCG level won’t be able to tell you much, but paired with your progesterone level and follow-up hCG levels (they should approximately double every 48-72 hours), you’ll be able to get a glimpse of what’s going on in your body.  LMP stands for Last Menstrual Period.
