If the values of both HCG and progesterone drop in early pregnancy, even if there is no bleeding, it may be a sign of embryonic dysplasia or even pre-eclampsia miscarriage, and the specific situation needs to be observed. 1. embryonic dysplasia: a slight drop in the values of HCG and progesterone may indicate that the patient has embryonic dysplasia without abdominal pain or bleeding, suggesting that the patient may have a biochemical pregnancy, and it is recommended to go to the hospital again Perform examination; 2. Pre-eclampsia: If HCG and progesterone drop significantly, consider having the precursor of miscarriage. If the HCG doubling is not good, it means that the gestational sac is not well developed and ultrasound should be done in time to determine the cause. If low progesterone is the cause of pre-eclampsia, progesterone should be replenished in time, either by oral progesterone or intramuscular progesterone injection, to avoid miscarriage after replenishing enough progesterone. During the period, you need to pay attention to bed rest, do not exercise strenuously, try not to have intercourse, and also need to increase nutrition in an appropriate amount.
