Pregnant women can bring their ID card to the local maternal and child health department – obstetrics department to register and create a pregnancy health card. The doctor will inquire in detail about the age, height and weight, any previous infectious diseases, any medical checkups done before pregnancy, etc., as well as the health condition of the pregnant woman, the health condition of her spouse, and the time of her last menstrual period to estimate the expected date of delivery, fill out a pregnancy health card, and make an appointment for the next maternity checkup, as well as inform the pregnant woman about the items to be examined and whether she needs to come to the hospital on an empty stomach, and make an appointment for the next maternity checkup. . The main purpose of establishing a pregnancy health card is to provide pregnant women with documented prenatal checkup items, prenatal checkup times, a reasonable number of prenatal checkups and pregnancy weeks systematically at a specific time not only to ensure the quality of health during pregnancy, but also to save health care resources.
