Clinical manifestations: early pregnancy reactions such as menopause, dizziness and fatigue after pregnancy; the uterus appears to be black plus sign; the breasts are swollen and painful, and the nipples appear to be Montgomery’s nodes. 2. Auxiliary examination: usually 8-10 days after fertilization, HCG can be detected in the serum of pregnant women; early HCG doubling time is about 1.7-2 days; at the same time, ultrasonography can be done for determining pregnancy, estimating the gestational age, and ruling out ectopic pregnancy, etc. If pregnancy is suspected, go to the hospital.
