What prenatal check-up should I do in the fourth month of pregnancy?

Down syndrome screening is a check-up that needs to be done in the fourth month of pregnancy. Generally, the risk of the fetus suffering from Down syndrome is screened by extracting the blood of the pregnant woman. In addition, you can check the fetal abdominal circumference, weight, blood pressure, blood routine test, urine routine test, and fetal heart rate. During pregnancy, you must pay attention to rest, improve nutrition, go to the hospital regularly for prenatal check-ups, eat more fresh vegetables and fruits, do not eat cold, spicy and irritating foods, maintain a happy mood, pay attention to the daily cleaning of the vulva, and wear cotton underwear.

Women should have at least 9-10 prenatal checkups during their entire pregnancy. The items for each checkup will be different depending on the month of pregnancy. The first prenatal check-up includes many examination items, and a guide for pregnant women should be established, including blood tests, urine tests, height, weight, obesity index or fetal heartbeat status.

In addition, the basic information of the fetus and mother also needs to be grasped. Several B-ultrasound examinations need to be carried out in the second trimester, including NT examination and four-dimensional color ultrasound. In addition, glucose tolerance and Down syndrome screening should be done in the second trimester of pregnancy, and invasive DNA testing should be done if necessary to determine whether the fetus has serious congenital diseases. In the later stages of pregnancy, routine physical examinations can be performed to monitor the fetal development and to detect whether the fetus has any serious malformations.

At 28 weeks of pregnancy, the pregnancy has entered the late stage, and the body structure of the fetus has basically grown and formed. The pregnancy checkups that need to be done during this period mainly include: 1. If the pregnant woman has not undergone glucose tolerance screening, a glucose tolerance screening can be carried out during this period to eliminate the possibility of gestational diabetes. 2. A four-dimensional color ultrasound needs to be done before 28 weeks of pregnancy. If you miss the best time, you can still do a four-dimensional color ultrasound examination at 28 weeks. 3. A color Doppler ultrasound examination is required to observe whether the fetus is in the right position in the uterine cavity and whether the embryo's adhesion site is normal. 4. The four-step abdominal palpation method can be used to check the height of the uterine fundus of the pregnant woman, the fetal position in the uterine cavity, and whether there are signs of premature entry of the fetus. 5. Improve the detection of fetal heartbeat and fetal movement during pregnancy.
