How long does it take to get an ultrasound during pregnancy?

Expectant mothers during pregnancy must go to the hospital for regular check-ups as required. At different stages of pregnancy, the items for check-ups in the hospital are different, such as routine urine tests, routine blood tests, etc. In addition, B-ultrasound examination is a must. When you first check whether you are pregnant, the most important way is B-ultrasound. B-ultrasound is currently a very important examination measure in clinical practice. How long after pregnancy can it be detected through B-ultrasound?

The physical health of pregnant women not only affects the pregnant women themselves, but also has a certain impact on the fetus. Pregnant women need to do B-ultrasound during routine prenatal check-ups, but when is the best time for pregnant women to do B-ultrasound? Today, the editor will tell you how long you need to wait before you can do an ultrasound during pregnancy, how many times a pregnant woman should do an ultrasound, and what to do if a pregnant woman is constipated.

How long does it take to do ultrasound during pregnancy?

Ultrasound examination can only see the gestational sac after 5 weeks of pregnancy, and the detection rate of the gestational sac reaches 100% at 6 weeks of pregnancy. The embryo can be seen at 6-7 weeks of pregnancy. At 49 days of pregnancy, when the diameter of the embryo is 2mm, the primitive heart tube beating can be seen. At 8 weeks of pregnancy, the human shape begins to take shape.

All organs are formed at the 14th week, hair begins to appear at the 15th week, and the uterus is about 16CM at the 16th week.

At the end of the 17th week, the baby's movements are restricted and fetal movements occur. The second scan (to reveal gender) is done at the end of week 21. The gender will be known at the end of the 22nd week.

If you do an ultrasound too early, it is not easy to see the gestational sac because it is too small. Not every doctor can make an accurate diagnosis, and it depends on the experience of the person doing the imaging, and the more they do, the better.

Ideally, it will be easily visible at 8-10 weeks of pregnancy. And if the B-ultrasound is done too early, the fragile and newly formed embryo will theoretically be shaken, which is not conducive to embryonic development. It is best to avoid doing B-ultrasound too early or multiple times.

How many times should pregnant women do B-ultrasound

1. The first check-up time is between 18 and 20 weeks of pregnancy. At this time, it can be determined whether it is a single or multiple pregnancy, and the fetal head circumference can be measured. Because the errors of many fetal ultrasound indicators are relatively small at this stage, it is convenient to verify the gestational age.

2. The second check-up is scheduled between 28 and 30 weeks of pregnancy. The purpose of doing B-ultrasound at this time is to understand the development of the fetus, whether there are any surface deformities, and to further understand the position of the fetus and the amount of amniotic fluid.

3. The last time is at 37-40 weeks of pregnancy. The purpose of the B-ultrasound examination at this time is to determine the fetal position, fetal size, degree of placental maturity, whether the umbilical cord is wrapped around the neck, etc., to conduct the final evaluation before delivery. If there are other special circumstances, you need to do an ultrasound in the early stages of pregnancy, but you should go after 6 weeks of pregnancy. Only then can the ultrasound show images. If you go too early, the ultrasound will not be able to show images.
