It is possible to have a baby without having a pregnancy file. The purpose of having a file during pregnancy is to record important information about the pregnancy throughout the pregnancy and to provide valuable medical reference for the doctor during hospital checkups or hospital deliveries. For example, at 6 weeks of pregnancy, an ultrasound will be performed to find out the size of the gestational sac and the location of the bed, and to check the four eugenics tests, blood type, routine blood tests, liver and kidney functions and folic acid utilization. In the 11-13 weeks of pregnancy, an ultrasound will be performed to understand the NT and fetal growth and development, which is an NT test and is exempted by the state. 14-19 weeks, a Down’s syndrome screening test will be performed, which is also an important test to screen for Down’s syndrome, i.e. congenital stupidity. Therefore, if you are pregnant and do not have a file, you should pay attention to the hospital and know what tests to perform in what cases.
