Early pregnancy tests are done in the gynecology department, and if it is determined that the pregnancy is intrauterine and the woman decides to have the baby, she will be transferred to the obstetrics department. After transferring to the obstetrics department, a series of examinations are needed to understand the condition of the pregnant woman and to evaluate the condition of the fetus in the uterus. If the fetus decides that she does not want to terminate the pregnancy, she will continue to see a gynecologist, and the abortion procedure will be carried out in the gynecology department. If you are having an abortion, you will also need to complete the preoperative examination, including ultrasound, blood tests, urine tests, leukorrhea routine, etc. The results of the examination are normal before you can arrange to have the operation. Under normal circumstances, it is necessary to go for examination after the menstrual period has exceeded a period of time. If the menstrual period only exceeds 2-3 days, and the intrauterine pregnancy cannot be detected within a short period of time, it is necessary to repeat the examination at a later stage.
