Is it safe to perform a vaginal ultrasound during pregnancy?

Transvaginal ultrasound generally refers to B-mode ultrasound examination via the vaginal route. Under normal circumstances, undergoing transvaginal B-mode ultrasound during pregnancy typically has no adverse effects. Detailed analysis is as follows:

Transvaginal B-mode ultrasound involves using ultrasound's physical properties through the vaginal pathway to assess pregnancy status and diagnose certain gynecological conditions. It is commonly used for diagnosing early pregnancy, prenatal screening during the first and second trimesters, and ectopic pregnancy. This type of ultrasound does not involve radiation and generally does not directly contact the uterus during the examination. It only slightly touches the cervix and typically poses no harm to the fetus, making it a suitable method for prenatal examination. If significant pain or discomfort occurs during the procedure, the physician should be informed promptly.

Pregnant women are advised to attend regular prenatal checkups at reputable medical facilities to monitor fetal growth and development in a timely manner. Additionally, maintaining a balanced diet by increasing intake of foods such as milk, pig trotters, and eggs, along with ensuring sufficient sleep, contributes to maternal health and fetal development.
