After pregnancy, women must do pregnancy checkups on time. Usually the first checkup is done at about 12 weeks of pregnancy to see if the pregnancy is intrauterine, and this checkup requires receiving the Pregnancy Health Handbook and doing various registrations and checks. The first official maternity checkup has more items, including the pregnant woman’s height and weight, blood pressure, liver function, electrocardiogram and so on, as well as the construction of a file to facilitate future checks. Most pregnant women start their first test around 12 weeks of pregnancy, and since they have entered a relatively stable stage at this time, the hospital will apply for a “Health Handbook for Pregnant Women” to facilitate future checkups. Since pregnant women are more excited and nervous when they have their first test, they should pay attention to regulating their emotions and not be too nervous so as not to affect the results of the test. In addition, pregnant women can dress loosely and it will be relatively more convenient during the examination.
