Progesterone value at 7 weeks of pregnancy usually fluctuates between 15-30ng/ml, and a slightly lower value may be physiological fluctuation. If it is obviously low, it may be related to luteal insufficiency, ectopic pregnancy, or congenital dysplasia of the embryo.
1. Slightly low progesterone: it may be physiological fluctuation, because progesterone is pulsatile secretion state. The growth curve of progesterone is not parallel to HCG, and even sometimes there will be a slight decline. Slightly low progesterone is not recommended for judging the development of the embryo.
2. If the progesterone is obviously low, it is considered to be related to luteal insufficiency, ectopic pregnancy, and congenital dysplasia of the embryo.
(1) Luteal insufficiency: After pregnancy, the ovaries secrete progesterone. Early pregnancy due to luteal insufficiency may lead to insufficient secretion of the hormone in the body, so low progesterone will occur.
(2) Ectopic pregnancy: If ectopic pregnancy has occurred, it may affect the hormone secretion in the body, and thus low progesterone may occur. Therefore, it should be analyzed together with HCG level and ultrasound.
(3) Congenital dysplasia of embryo: If the embryo is congenitally dysplastic, it may lead to the reduction of congenital progesterone, so this situation will occur.
If the progesterone is low and the embryo is still alive, the doctor should evaluate and decide whether to supplement the progesterone or not. During the pregnancy, you need to observe your body more often, and if there is bleeding, abdominal pain and other symptoms, you need to consult a doctor in time.
