Ultrasound examination is essential during pregnancy. Ultrasound examination can confirm whether a woman is pregnant in the early stages of pregnancy. In the process of pregnancy, ultrasound examination can also screen for fetal development abnormalities, as well as understand the development of the placenta and the amount of amniotic fluid. There are also many times of B-ultrasound examination during pregnancy. So, how many normal fetal buds can be detected in the second ultrasound examination?
It is normal for the size of the second trimester embryo to be between 13mm and 17mm. The size of the fetal bud needs to be determined based on the woman's pregnancy time, and it can usually be seen around six or seven weeks of pregnancy. Second ultrasound refers to the second ultrasound examination. Under normal circumstances, women need to undergo three or four ultrasound examinations during pregnancy. If there are special circumstances, such as women experiencing illnesses or abnormalities, the frequency of ultrasound examinations will be higher.
If there are no fetal buds or fetal buds have stopped developing during the examination, it should be taken seriously by women. There are many reasons that can cause this type of fetal abnormality, such as chromosomal abnormalities, female infectious diseases, female endocrine disorders, and poor uterine development.
The first ultrasound examination is conducted around four weeks of pregnancy, while the second ultrasound examination requires an interval of about two weeks from the first one. Women should regularly undergo various examinations during pregnancy in order to understand their physical health status and constantly monitor the development of the fetus.
