How many times should I do ultrasound during pregnancy?

From the day of pregnancy, pregnant women are full of expectations for the baby in their belly, and mothers often imagine what the baby will look like after birth. With the improvement of modern medical technology, many mothers can't wait to know more about the fetus in their belly, so they choose to do B-ultrasound. This can not only satisfy their curiosity about the fetus in their belly, but also let them know the growth and development of the fetus. So, how many B-ultrasounds should be done during pregnancy?

Generally speaking, 2 to 3 ultrasounds are sufficient during the entire pregnancy, but the doctor will increase the number of examinations based on the patient's specific situation. You mentioned that you had ultrasounds at 12 weeks and 19 weeks. Under what conditions did the doctor recommend you to do it? If there are no special circumstances, you should do it again in the late pregnancy to understand the maturity of the fetus to determine the mode of delivery. Everyone knows that B-ultrasound is different from other X-rays, and sometimes it is necessary to do an ultrasound examination during pregnancy. Some pregnant women are worried that frequent B-ultrasounds will affect the fetus. Is this worry necessary? Most medical procedures during pregnancy are based on the results of animal experiments. Doctors do not have data from human experiments, so they will weigh the pros and cons and decide to conduct relevant examinations based on the patient's specific circumstances.

Ultrasound examination is usually not required in early pregnancy (especially before 8 weeks of pregnancy). Because this is a critical period for the formation of various organs of the fetus, it is also an important stage that can easily lead to fetal malformations. Except for patients with vaginal bleeding and abdominal pain (abnormal pregnancy needs to be excluded, such as ectopic pregnancy, hydatidiform mole, missed abortion), patients with pelvic mass or uterine fibroids before or during early pregnancy, B-ultrasound examination is needed to assist in diagnosis and provide a basis for future treatment. For those whose menopausal age is unclear and whose gestational age is difficult to estimate based on symptoms and signs, it is generally more appropriate to examine them between 10 and 13 weeks of pregnancy.

In the middle and late stages of pregnancy, the fetal organs have already formed, so ultrasound examination is relatively safe. Regular ultrasound examinations should be performed starting from the 20th week of pregnancy, but it is best not to do more than 3 ultrasounds during the entire pregnancy.

Nowadays, pregnant women will definitely choose to have a B-ultrasound examination so that they can understand the growth and development of the baby in their belly in time, and learn about any problems with the fetus, whether there are any lesions, etc. According to the introduction above, female friends also know that it is better to do B-ultrasound several times during pregnancy. If it is not necessary, there is no need to do B-ultrasound examination frequently.
