Progesterone and HCG reports are usually available on the day the blood is drawn. After pregnancy, the body secretes a special hormone called chorionic gonadotropin, or HCG for short, which doubles as the number of days after menopause increases, so monitoring blood levels of HCG can reflect the activity of the embryo, but ultrasound examination by an Obstetrician and Gynecologist is needed to determine if the pregnancy is intrauterine and to determine whether the embryo is developing in accordance with the number of days after menopause. There is no specific value for progesterone after pregnancy and it varies greatly from person to person, so it is not a routine test if the patient does not have obvious signs of pre-miscarriage. However, progesterone supplementation may be indicated if there is a previous history of preeclampsia or if there is a history of poor pregnancy and labor.
