Twins do best in four weeks

The best time for pregnant twins to do four-dimensional color ultrasound is 24 weeks of pregnancy. It is recommended to go to the hospital for four-dimensional color ultrasound examination within 22 weeks of pregnancy. Because the number of people examined is relatively large, it is recommended to make an appointment in advance so as not to miss the best time for examination. Because the baby is too big, it is easy to see incomplete four-dimensional color ultrasound, which will cause the diagnostic significance to be unclear.
