Initial symptoms of pregnancy include menopause, early pregnancy reaction and other symptoms. 1. Cessation of menstruation: Healthy women who usually have regular menstruation and a history of sexual intercourse should consider pregnancy once they have menstrual periods, and pregnancy should be highly suspected when menstruation has ceased for more than 10 days. 2. Early pregnancy reaction: dizziness, fatigue, loss of appetite, morning sickness and other symptoms appear around 6 weeks after menopause, which is called early pregnancy reaction. Most of them disappear after 12 weeks of pregnancy. 3. Other symptoms: the anteriorly tilted and enlarged uterus presses the bladder in the pelvis, resulting in frequent urination; the breasts can be swollen and painful to the touch, and Montgomery’s nodes appear around the nipples. At 6-8 weeks of pregnancy, the isthmus of the uterus is extremely soft and it feels like the cervix is not connected to the uterus, which is called the Hega sign. If you experience any of these symptoms, go to the hospital for a pregnancy test and ultrasound to determine if you are pregnant as well as to estimate your gestational week.
