Low progesterone, but normal human chorionic gonadotropin

Patient's question:

Pregnancy week 6 to 8, progesterone P is only 18.19, while human chorionic gonadotropin subunit B is 77515

Doctor's answer:

Progesterone is a progestogen that can transform the endometrium from the proliferative phase to the secretory phase, further thickening the endometrium to facilitate the development of the fertilized egg. At the same time, it can inhibit uterine contractions, playing a specific role in maintaining pregnancy. Low progesterone levels may lead to miscarriage.
Recommendation: Progesterone is secreted by the embryo. When progesterone levels are low, medications such as progesterone and vitamin E may be used for pregnancy maintenance treatment.
Progesterone is not present in food and does not have a role in maintaining pregnancy. However, during pregnancy maintenance, it is advisable to avoid spicy, irritating, and cold foods to prevent uterine contractions and affect treatment efficacy.
