The probability of these 4 types of pregnant mothers passing these two tests will be very low:

1. Pregnant women of advanced age. The older the pregnant mother, the more various fertility risks will increase. The probability is also different at different ages, and the older the age, the higher the probability.
Therefore, for advanced mothers over the age of 35 or expectant mothers with other abnormal birth history, it is necessary to consult a doctor whether they need to have amniocentesis surgery.
Because amniocentesis can further determine the health of the fetus, but this is still risky, although the risk is small, pregnant mothers still need to obtain the consent of the doctor to carry out it.
2. Pregnant women who eat very casually. It is necessary to avoid eating during pregnancy, and the healthy diet of pregnant women will be more beneficial to the growth of the fetus. If you eat very casually during pregnancy, you have a very high chance of developing Down syndrome.
3. Pregnant women who often stay up late. After pregnancy, many pregnant mothers will become less likely to move around.
Especially for the pregnant mothers who were originally very homely, now they are staying at home all day and night to play mobile phones, chasing dramas, and sometimes even staying up late, and the next day they will sleep until very late before waking up.
And such a habit when you do Tang Si, it is likely to lead to inaccurate results.
4. Pregnant women with bad habits. You can't smoke and drink alcohol during pregnancy, not only during pregnancy, even if you are pregnant, you can't smoke and drink, even if you are second-hand smoke and cold drinking, you must be careful.
Pregnancy is a big event in life, we better be responsible for our children and be a self-disciplined pregnant mother. If you have some bad habits like eating cold food, smoking and drinking, it is best to change it early!
Therefore, pregnant mothers should check smoothly and smoothly, and the fetus is healthy and healthy, so they must pay more attention to these aspects.
