Most women have early pregnancy reactions around 6 weeks after menopause, which can be confirmed by urine pregnancy test, blood sampling and gynecological ultrasound. Early pregnancy reaction is a normal physiological phenomenon after pregnancy, and some women can experience early pregnancy reaction such as morning sickness, vomiting, breast swelling, loss of appetite and weakness after menopause. However, there are some women who do not have early pregnancy reactions and can eat, work and study normally during early pregnancy because the elevated chorionic gonadotropin level in their bodies is not obvious. When women have early pregnancy reactions, they should pay attention to a light diet, take more rest, prohibit sexual intercourse, avoid stimulation by external unfavorable factors, and go to the hospital for examination and treatment if they have lower abdominal pain or a small amount of vaginal bleeding. After the third month of pregnancy, the early pregnancy reaction will gradually decrease as the fetus grows and develops.
