Women need to undergo ultrasound examination during pregnancy, and some pregnant women may be told by doctors that they are pregnant with twins after the examination, which is very surprising for pregnant women and their families. However, when women become pregnant with twins, the pregnancy becomes even more difficult and premature birth is more likely. So, can early pregnancy ultrasound detect twins?
If an ultrasound is performed in early pregnancy, twins can be detected. Usually at 8 weeks of pregnancy, a B-ultrasound examination can not only confirm intrauterine pregnancy, but also determine whether it is a twin. If two gestational sacs are detected through ultrasound, it can be basically confirmed that the woman is pregnant with twins.
Women should go to the hospital for a chorionic villi scan at 12-14 weeks of pregnancy. Through this examination, it can be determined whether twins are sharing the same placenta. Sometimes, both fetuses may use their own placenta. After conducting a chorionic scan, the risk of complications in twins can be determined.
Performing ultrasound screening for twins is much more difficult than for singleton pregnancies. This is because when twins undergo examinations, there is always a situation where one is in front and the other is behind. This will make it difficult for doctors to see the condition of the fetus behind them. If one of the fetuses' heads is under the pregnant woman's pelvis, it is also easy to affect the doctor's examination and cause some errors.
