Under normal circumstances, you can go to the hospital for a checkup around 6-13 weeks of pregnancy, which is the first maternity checkup. The routine mandatory items for the first maternity checkup include routine blood and urine tests, blood type, hepatitis, syphilis, HIV screening, and electrocardiogram. Ultrasound examination in early pregnancy can determine the intrauterine pregnancy and the exact gestational week to understand the growth and development of the fetus in the uterine cavity. During this period, a pregnancy care booklet needs to be established to assess the risk factors during pregnancy. At the same time, the pregnant woman needs to be given nutritional and lifestyle guidance, such as avoiding exposure to toxic and harmful substances and pets, using medication carefully, changing poor lifestyle habits, avoiding high-intensity work and high-noise environments, maintaining mental health, and paying attention to folic acid and vitamin complex supplementation. In addition, if a pregnant woman experiences severe abdominal pain, vaginal bleeding and other special conditions, she should go to the obstetrics department of a regular hospital for examination at any time, without waiting for a certain number of weeks of pregnancy before going for examination.
