Why does the fetus not move when ultrasound is done at 12 weeks of pregnancy?

12 weeks is the third trimester of pregnancy. During this period, the baby has not yet fully formed. So there is no way to move yet. The baby also grows slowly little by little with the month, and it is checked well every period. Welcome to a healthy baby.

Because the fetus in the mother's womb moves irregularly, sometimes it only moves a few times and then does not move, and the B ultrasound may not move because the fetus does not move at that time.

There are several possibilities for B ultrasound at 12 weeks of pregnancy: (1) the fetus is still too small at this time, the activity is slight and not obvious, and it looks like it is not moving, (2) if the fetus is sleeping at the time of the examination, then the fetal movement cannot be captured.

The 12-week baby is still too small, the overall length is only about 7cm, the activity is not obvious, and the number and amplitude of activities are not as frequent and large as in the later stage, so the pregnant mother can hardly feel it.

There are two reasons, one is that it may be because the fetal baby is sleeping when the ultrasound is done, so it is difficult to detect the baby's fetal movement during the examination; Second, it may be because the fetus is small in size and has a relatively gentle attitude, which cannot be detected by ultrasound.

At 12 weeks of pregnancy, the fetus does not move when B overtime, and it is possible that the fetus is sleeping. You can get up and climb the stairs, take a walk or eat some sweets to make your baby move, so that you can have a better ultrasound examination.

When the fetus does not move at 12 weeks of pregnancy, it is very likely that the fetus has an abnormality, or the fetus is gone, and the fetal heart rate is stillborn.

12 weeks of pregnancy is only more than three months, the fetus has not yet formed, it is normal if it does not move, this is not to worry, generally to four or five months, you can start to feel the fetal movement.

At 12 weeks of pregnancy, the baby has been formed, so let's take a look at the cute appearance.

At 12 weeks of pregnancy, we should need to do a B-ultrasound examination in our hospital, and the main items of this B-ultrasound examination include: fetal head and hip diameter length (CRL), fetal nuchal translucency thickness (NT), and fetal nasal bone. The aim is to assess whether the fetus has an increased risk of Down syndrome, and in the eyes of some researchers, NT values are also associated with structural abnormalities of the fetal heart.

At this point, let's talk about a number, NT is increased with CRL at 11-13+6 weeks of pregnancy, and the normal value is increasing, not static. About what, it still doesn't make sense, it needs to be combined with CRL.

Is it okay not to do NT, of course, after all, it is an alternative prenatal examination project, and it has not been popularized in many places, but it is beneficial to do NT, which can detect fetal abnormalities early and rule out fetal malformations early.

In summary, it is best to have an NT test at 12 weeks of pregnancy, which can detect fetal abnormalities early and improve the detection rate of fetal abnormalities. Conditional mothers should still do it. Good luck getting pregnant.

At 12 weeks of pregnancy, the fetus has slowly taken shape, that is to say, 12 weeks is already 3 months, so the early dangerous three months are basically completed at this stage, but the necessary examinations must be done.

You should go to the hospital for a detailed examination of the NT and nasal bone, which is also an important deformity removal item in the early stage.

It is very important to go to the community to create a card, so that it is easy to record the data of each prenatal checkup and the time of the next prenatal checkup. Moreover, the card building manual is necessary for the baby to be vaccinated after birth and go to school.

3. Blood examination, items: blood routine, infection items, coagulation items, blood type, hepatitis B two and a half, hepatitis B antibody, etc., electrocardiogram, urine routine, etc.

4. B-ultrasound monitoring of fetal development, fetal heart rate, etc.

5. The hospital will monitor the health of you and your fetus safely and professionally, so be sure to go to the hospital.
