I feel uneasy every time I go for a prenatal check-up after pregnancy. Even if I pass the customs, I will be worried. What about next time? The fetus has not been deformed' high incidence', so it is impossible to be careless. Some mothers may be confused. What is the high incidence of fetal malformation? What should I pay attention to?

Pregnancy until this month is a hurdle in pregnancy.

In the process of embryonic development, especially the 3-8 weeks of pregnancy (the 5th 5- 10/0 week of the last menstruation), this period belongs to the organ formation period, also known as the teratogenic sensitive period. Fetal brain begins to develop after conception 15-27 days, with eyes on 24-29 days, heart on 20-29 days and limbs on 24-36 days. During this period, it is most likely to be deformed by teratogenic factors. After pregnancy 1 1~40 weeks, the embryo enters the fetal stage, and its organs and tissues gradually develop and shape, and its sensitivity to harmful substances is reduced, which is relatively safe, but not absolute. In the third trimester, the mother is infringed, which will also affect the development of fetal intelligence.

In the first three months after pregnancy, the embryo is in a period of rapid differentiation. During this period, a little external stimulus (even a very small stimulus) may cause abnormal differentiation. Therefore, the first three months of pregnancy is also the peak of abortion. Clinical statistics show that the proportion of threatened abortion in the first three months is above 90%.

How to prevent fetal malformation in early pregnancy?

Fetal malformation is not a single factor, but related to the behavior of pregnant mothers, the lack of certain substances (folic acid) in the body and the environment.

1, folic acid supplementation on time

In the first three months of preparation for giving birth to a baby, it is recommended to supplement folic acid until the third month after pregnancy, that is, 6 months. It takes 4~6 weeks for folic acid to enter the body and act on it, which can ensure that folic acid in the body remains at a relatively stable level when the mother is pregnant. Moreover, folic acid supplementation can also prevent fetal neurovascular malformation and neonatal neurovascular defects after birth.

2. The environment is healthy

In the early stage of pregnancy, the environment where the pregnant mother is located is very important, especially where she has been for a long time. Some pregnant women still insist on going to work after pregnancy. If the environmental radiation is small, the problem is not big. They can also exercise and improve their mood. However, if there are workplaces in radiation areas, such as X-rays, heavy metals, heavy pollution and other environments, it is still recommended to transfer.

Ps: If you have a pregnancy plan, it is recommended to change jobs six months in advance.

3, careful medication according to the doctor's advice

Try not to take antibiotics during pregnancy, especially in the early stage of pregnancy (including pregnancy preparation). If you catch a cold accidentally, as long as it is not too serious, you can drink more hot water, ventilate frequently and keep warm.

Just pregnant will also have some symptoms similar to a cold. If you have a pregnancy plan, it is recommended to consult a doctor before taking the medicine and do relevant tests to determine whether you are pregnant.

When I was pregnant with Dabao, I felt very tired, weak and had a runny nose at first. I thought it was a cold, and I didn't know I was pregnant until I went to the hospital for examination. The doctor asked me to cook onion, ginger and garlic three times a day for three days, and I got over my cold.

What should I pay attention to in the early pregnancy?

Our hometown says that not telling outsiders in the first three months of pregnancy will anger the fetus and be bad for the baby. At first I thought it was superstition, but then I thought about it myself. The first three months were not very stable. It's really hard to tell others too early in case of an accident. Understanding from this aspect is also scientific.

Emotional instability in early pregnancy will increase the probability of fetal cleft lip and palate and give birth to a' rabbit lip' baby.

Due to the change of progesterone level in the first trimester, the expectant mother's mood fluctuates greatly, and she often hurts herself secretly. Sometimes when a leaf falls, she will cry. I don't like to say anything, but I will sulk myself and my family should understand. Husbands should spend more time with each other and try to help them solve problems.

In addition, there are concerns about the health of the fetus, which will make pregnant mothers very uncomfortable. 7~8 weeks, you can go to the hospital for B-ultrasound examination to understand the development of the fetus. After hearing fetal heart sounds, pregnant mothers will feel much better.
