Ultrasound: Ultrasound is usually done between 6-7 weeks after pregnancy, or earlier if there is abdominal pain, vaginal bleeding, etc. The purpose is to confirm the location of the fetal sac. The purpose is to confirm the location of the fetal sac, whether the pregnancy is intrauterine or ectopic, whether there is a fetal heart, the number of embryos, whether it is a single or double or multiple, etc., but also to observe the uterus, fallopian tubes, ovaries to confirm that there are no abnormalities. 3. Blood pressure: Every labor and delivery checkup should measure blood pressure in order to detect pregnancy hypertension and other diseases in time. 4. Weight: As pregnancy increases, weight will change. Timely measurement of weight can reflect the normal development of the baby during pregnancy. 5. Biochemical and other tests: blood test, urine test, liver function, fasting blood sugar, blood type, kidney function, syphilis spirochete, HIV screening and other tests. If the pregnant woman herself also exists in certain high-risk factors, it is also necessary to increase the examination program.
