Pregnant women need to go to the local community health service center or township health center to establish maternal health records in a timely manner. The process of establishing the records is relatively simple, and is actually a process of filling out personal information. During the establishment of the file, the maternity doctor will ask for information such as maternity history, last menstrual history, time of the first examination, whether there are test results, history of previous diseases, family history, etc. The pregnant woman should provide detailed and accurate information. During the examination, obstetrical examinations should be performed at the same time. If relevant examinations have been done, the pregnant woman should provide relevant information, and if no examinations have been done, she should cooperate with the doctor for these examinations.
