Can you see the baby's health status through B-ultrasound in the first trimester? B-ultrasound in the first trimester can only see the embryo and fetal heart, and can't determine whether the fetus will be healthy in the future. At this time, we can only see if the child has a fetal heart. The baby's health will take three months to take shape, but it is not very clear. The accuracy of four-dimensional color Doppler ultrasound for four months is higher. Pregnant for more than 40 days, no baby, only fetal heart and germ can be seen. So wait until April and May to do accurate screening!
Does B-ultrasound have radiation during pregnancy? B-ultrasound is an ultrasonic wave that does not produce ionizing radiation, which is different from radioactive examination such as X-ray. Generally, B-ultrasound has no effect on fetal development and pregnant women. So far, there is no report about fetal malformation caused by B-ultrasound, and the intensity of B-ultrasound is very low, which will not cause damage to the fetus. On the other hand, if you don't find yourself or your fetus abnormal in time because you are afraid of this examination, you will lose big because of small.
During IVF, B-ultrasound should be done frequently, because in a physiological cycle, the physiological characteristics of women will change with time. Only through B-ultrasound can we know the real-time endometrial thickness, endometrial type, the number of follicles and the growth and development of each follicle, thus promoting all aspects of IVF. If everything is normal after the check-up, then you just need to follow the normal pregnancy check-up process. Ultrasound examination is a non-invasive examination, which will not affect your own health and fetal development, so don't worry too much.
When to do B-ultrasound during pregnancy? Generally, the time of these five ultrasonic examinations is:
6-7 weeks (early pregnancy examination): mainly confirm the gestational age, see whether it is intrauterine pregnancy or ectopic pregnancy, singleton or twin (confirm the nature of chorion) or multiple births, and whether the embryo is dead or alive.
1 1- 14 weeks (NT examination): mainly check NT and draw blood for Down's screening in early pregnancy.
20-24 weeks (systematic ultrasound examination): It is mainly to screen the fetal giant malformation to find out whether there are any major structural defects in the fetus.
About 32 weeks (routine examination): it is mainly to monitor the growth and development of the fetus and check whether the fetus has growth restriction, amniotic fluid and umbilical cord.
About 37 weeks (routine examination): to judge the fetal development, amniotic fluid volume, placental maturity, whether there is umbilical cord around the neck and fetal position; Fetal biparietal diameter, head circumference, abdominal circumference and femur length were measured, and fetal weight was estimated to determine delivery mode.
