The symptoms of new pregnancy are as follows: 1. menopause: if a person who has regular menstruation has delayed menstruation for 10 days or more, it is considered pregnancy and should be diagnosed in hospital in time; 2. early pregnancy reaction: after pregnancy, mostly after 6 weeks of menopause, pregnant women will experience nausea, vomiting, weakness, drowsiness, dizziness and acidity and other early pregnancy reactions due to the change of hormone level in the body, and some patients will have emotional changes. 3. Breast changes: In the early stage of pregnancy, pregnant women will feel a slight swelling and pain in their breasts, and their breasts will gradually increase in size, and they will also have enlarged nipples and deepened nipple areola coloring. 4. To sum up, if women experience menopause and nausea, vomiting and other related symptoms after intercourse, they can go to the hospital for a blood HCG test, and if there is an increase in HCG and progesterone, it mostly indicates pregnancy. At around 6 weeks of pregnancy, the diagnosis can also be confirmed with ultrasound. Early pregnancy is an important period for fetal formation and fetal organ differentiation. Pregnant women should maintain a relaxed mood, take folic acid to prevent fetal neural tube abnormalities, and prohibit sexual intercourse in the first 3 months of pregnancy to avoid stimulating the uterus and causing miscarriage.
