Progesterone at 10 ng/mL at 7 weeks of pregnancy is serious and carries a risk of miscarriage and requires aggressive treatment. Serum progesterone increases in pregnancy and rises steadily with weeks of gestation, favoring embryo implantation and maintenance of continued pregnancy. Serum progesterone at 25ng/mL at 7 weeks of pregnancy is normal, when the level of progesterone is low, there is a high risk of early miscarriage, so progesterone at 10ng/mL at 7 weeks of pregnancy is serious, and it should be followed by the doctor’s advice to actively supplement progesterone treatment. Progesterone is mainly secreted by the corpus luteum in early pregnancy, and is mainly secreted by the placenta after 8 to 10 weeks of pregnancy. When the corpus luteum is not functioning, the amount of progesterone secreted will be reduced, and it is necessary to actively give progesterone, dydrogesterone and other medications under the guidance of the doctor, and after treatment, the level of progesterone should also be rechecked, and ultrasound to understand the development of the embryo. When the progesterone is 10ng/mL at 7 weeks of pregnancy, combined with the rise in blood HCG values, it is necessary to actively treat under the guidance of the doctor.
