Can I do B-ultrasound when I am pregnant?

When a woman becomes pregnant, she very much hopes that she and her baby are safe. Of course, she hopes to see changes in the baby in all aspects. The current medical level can observe the changes in the fetus at various stages of development through B-ultrasound. Therefore, pregnant women must go to the hospital for B-ultrasound examinations at different times during pregnancy, and the B-ultrasound examinations must be done according to the doctor's schedule.

Can I do B-ultrasound when I am pregnant?

Case 1

Under normal circumstances, pregnant mothers should have an ultrasound examination in the early stages of pregnancy (around 12 weeks of pregnancy). Pregnant mothers should avoid having B-ultrasounds too early or too many times. Doing an ultrasound too early may cause the fragile, newly formed embryo to be shaken, which is not conducive to embryonic development. B-ultrasound in early pregnancy is to confirm whether the pregnancy is ongoing and how many days the pregnancy has lasted, to provide a reliable basis for determining the expected date of delivery, and to promptly detect any abnormalities in embryonic development.

Case 2

The second B-ultrasound examination is usually scheduled in the middle of pregnancy (around 20 weeks of pregnancy). At this time, there is relatively more amniotic fluid in the uterus, the fetus is of moderate size, and there is a large space for movement in the uterus. For B-ultrasound examination, there is better contrast, and the various organs of the fetus can be clearly seen. More obvious malformations, such as congenital heart disease, anencephaly, hydrocephalus, spina bifida, abdominal wall defect, short limbs, polycystic kidney disease, and gastrointestinal atresia are easy to detect. If necessary, timely treatment or termination of pregnancy can be carried out.

Case 3

The third B-ultrasound examination should be arranged in the late pregnancy (around 28 weeks of pregnancy), mainly to understand the development of the fetus in the uterus and to check again whether the fetus has any malformations. Because some diseases may not be discovered in time during the second trimester of pregnancy by ultrasound examination. If the pregnant mother has not given birth two weeks after the due date, the doctor may recommend another B-ultrasound to understand the condition of the placenta, amniotic fluid, fetal position, etc., which will help the doctor decide which delivery method is safe. If the pregnant mother suffers from certain diseases, ultrasound examination is more important. The frequency and time of ultrasound examinations during pregnancy should be determined by the doctor according to the pregnancy situation.
