A 31-week maternity checkup entails routine health checks, ultrasound, blood and urine tests, and more. At 31 weeks of pregnancy, you have reached the late stage of pregnancy, at which time you will have a labor and delivery checkup once every 2 weeks. During the checkups, routine health checks such as blood pressure, weight, uterine height, abdominal circumference, fetal position, fetal heart rate, etc. will be performed to check the development of the fetus and whether the pregnant woman has pregnancy complications such as high blood pressure during pregnancy. Pregnant women also have to do some auxiliary examinations, such as ultrasonography, to check fetal growth indicators, amniotic fluid, placenta and other conditions. And routine blood and urine tests are performed to check whether the pregnant woman has anemia, proteinuria and other abnormalities. During the 31-week maternity checkup, the doctor will provide pre-delivery lifestyle guidance and some knowledge related to labor and delivery, as well as instruct the pregnant woman to count her own fetal movements and monitor the intrauterine condition of the fetus. Pregnant women need to follow the schedule of maternity checkups and have regular checkups. At the same time, keep a calm mind and consult a doctor if you feel unwell.
