Patient's question:
I am very scared when this happens. I often have lower abdominal pain and don't know how to solve it, so I came here for consultation. Please ask how long pregnant should one be before undergoing fetal anomaly screening?Doctor's answer:
During the examination, ultrasound, although ultrasound is ultrasound transmission and non-radiation, cannot be done arbitrarily during pregnancy. Three times during pregnancy are enough. The first time, during the 3rd and 4th months of pregnancy, this time it can detect whether it is a single or multiple pregnancy, and can also detect the size and development of the fetus. The second time, in the middle of the 6th month, to understand the position of the fetus, the amount of amniotic fluid, and whether there is a malformation. The third time, during the last 2-3 months of pregnancy, the fetal position, size, maturity of the placenta, and whether the umbilical cord is, to prepare for prenatal care. It is best not to do an ultrasound examination in the early stages of pregnancy. In special cases, such as bleeding, it is necessary to check. It is best not to exceed 5 times.
