1. About 50 days pregnant
At the beginning of the pregnancy of about 50 days, it is necessary to check whether the fertilized eggs are growing in the womb or outside the uterus through ultrasound, which is very critical during this period of ultrasound examination. Because if it is an ectopic pregnancy, it will cause heavy bleeding and threaten the vital signs of the pregnant woman, and if it is confirmed that the fetal heartbeat can be seen in the womb, then the fetus can continue to grow and develop.
2. Pregnancy 11 weeks - 13 weeks + 6 days
When pregnant for 11 weeks - 13 weeks + 6 days, it is recommended to have an NT test. The time window for NT examination is only two weeks, and it is recommended for pregnant women with high risk factors, such as elderly pregnant women after the liberalization of the two-child policy, pregnant women who have previously had a bad maternal history, and pregnant women with some comorbidities.
3. 22-26 weeks pregnant
Pregnancy 22-26 weeks at this time should be said to be the best time to see the baby, the doctor will do a complete fetal structure screening, from head to toe to collect a lot of images of the baby, carefully observe whether there are major problems. To do a good job in this examination, you need to be good at the right time and place - the doctor has the skills, and the baby must cooperate. It is best for your baby to be awake and able to move, not to sleep on his stomach, or preferably to sleep with his face facing the doctor. If the doctor feels that the baby is not moving in the mother-to-be's belly, he will let the mother-to-be go out for a circle, take a walk back, and wait for the baby to turn over and look at it again. Therefore, the inspection time may be longer, which is to make the inspection more accurate and complete.
4. 28-32 weeks pregnant
At 28-32 weeks of pregnancy, as the fetus grows up, the fetal bones are obscured, the fetal position is relatively fixed and other factors, the examination cannot be comprehensive and meticulous, but only a relatively rough deformity screening, as well as screening for some malformations that occur in the third trimester.
5. Full term, before birth
Prenatal ultrasound assessment (term, prenatal), this examination is to determine the fetal position of the fetus, evaluate the growth and development indicators of the fetus and the fetal weight, it should be emphasized that the detection rate of malformation screening at this time is very low, mainly to prepare for the final delivery.
