Usually the first pregnancy test will have an overall analysis of the instructions. Before the 13th week of pregnancy, you need to go to the local health center or community service center on an empty stomach to build a health care booklet for pregnant women and complete the first delivery test. The content of the health care booklet includes basic information, height and weight, hepatitis B surface antigen, syphilis, AIDS, liver and kidney function, blood routine, blood type, urine routine and ultrasound and other related tests. The doctor analyzes the overall situation of the mother based on the information collected and tells the mother verbally or on paper the relevant precautions to take. For example, whether she is an advanced maternal age, whether her body mass index is within the normal range, whether she has any disease transmitted vertically, whether she is anemic, etc. will be explained in detail and the time of the next delivery test will be explained. It is recommended to keep your body and mind happy during pregnancy, keep up with your checkups, and go to the hospital if you feel unwell.
