The 8 days of pregnancy should refer to 38 days of menopause, when the level of human chorionic gonadotropin in the blood is about 5000-50,000 IU/L. Because it takes about 1 week for the fertilized egg to form and move from the fallopian tube abdomen to the endometrium and then successfully implant, and also has great individual differences, the body usually starts to secrete hormones only after implantation, and only then will the hormone levels be monitored in the blood. The hormone levels are monitored to know that the fetus is growing and developing normally. However, if there is a late onset of labor, the hormone levels detected in the blood may be very low, so continuous monitoring of the hormone levels in the blood is needed. In addition to hormone tests in early pregnancy, ultrasound examinations need to be completed in a timely manner, mainly to rule out the possibility of ectopic pregnancy. Currently most women have reproductive system infections and are prone to abnormal pregnancies.
