When is the best time to do ultrasound in early pregnancy?

During pregnancy, you should pay attention to B-ultrasound, as it can be quite harmful to the baby, so it should not be done lightly. However, you need to go to the hospital for B-ultrasound examination during pregnancy, so it is okay to do B-ultrasound during regular prenatal checkups. However, don’t do B-ultrasound frequently because of excessive worry and anxiety. Let’s take a look at some relevant introductions about B-ultrasound during pregnancy.

From the necessity and economic perspective of the examination, it is advisable to have no more than two necessary normal pregnancy examinations. The first examination is at 18 to 20 weeks of pregnancy. At this time, the fetus already has a rudimentary shape. The focus of this examination is to rule out true fetal malformations, so it is an examination that must be done.

Most obstetricians and gynecologists do not recommend ultrasound for pregnant women within 18 weeks of pregnancy, especially within 12 weeks of pregnancy. However, if a pregnant woman experiences worrying conditions in the early stages, such as vaginal bleeding or sudden abdominal pain, using B-ultrasound to determine whether the embryo is alive and whether the pregnancy can continue, and whether there is an abnormal pregnancy like ectopic pregnancy or hydatidiform mole, is the most direct and reliable means, and it is wise to actively cooperate with the doctor's examination.

The second check-up can be done when necessary to understand the growth and development of the fetus, the condition of the amniotic fluid, and whether there are any abnormalities in the placenta in the late pregnancy. If the pregnancy is abnormal, the number of B-ultrasound examinations will be determined based on the condition. For example, when there is too much amniotic fluid, the amount of amniotic fluid may need to be measured frequently before and after treatment. If the pregnancy exceeds 40 weeks, B-ultrasound examinations may be required 1 to 2 times a week to measure the amount of amniotic fluid and evaluate the condition of the fetus in the uterus.
