If you are pregnant after having intercourse three days after the passage of water, the pregnant woman needs to visit the hospital to find out about the passage of water and the medications used after the procedure. If there are no unfavorable factors, it is recommended to continue the pregnancy. Patients can strengthen their health through the following measures: 1. Regular maternity check-ups: the mother should go to the hospital regularly for maternity check-ups to observe the development of the fetus. During this period, patients should seek medical attention immediately if they have any discomfort; 2. Supplementation: Pregnant women should supplement multivitamins (with folic acid) and calcium, etc., under the guidance of professional doctors, to promote fetal neurodevelopmental nutritional drugs to prevent fetal developmental malformations; 3. Diet regulation: Maternal intestines become sensitive after pregnancy, and any discomfort in diet can easily cause diarrhea and other adverse symptoms. Therefore, it is recommended that pregnant women eat a varied diet and avoid spicy, cold, greasy food, such as chili, ice cream, etc.. You can eat more vitamin-rich foods, such as carrots and kiwi, in order to enhance maternal health. 4. Prevent infection: After surgery, the cervical opening of the patient is relaxed, and due to the large amount of estrogen and progesterone produced in the body during pregnancy, the content of lactic acid bacteria in the vagina is reduced, and germs can easily invade and cause infections, such as pelvic inflammatory disease and vaginitis. Therefore, pregnant women should avoid taking a sitz bath and change their intimate clothes regularly to avoid infection. 5. moderate exercise: according to their physical condition and preferences, they can choose mild exercises such as yoga and walking to enhance blood circulation and improve metabolism in the body.
