There is no obvious difference in performance between boys and girls. The following characteristics are the experience summary of pregnant mothers, which is accurate to some extent, but not 1% accurate. In fact, it is impossible to have a 1% accurate basis only from the appearance.

1. Hair growth

Male babies secrete more hormones, which will affect the endocrine of pregnant women and may promote the growth of hair on their stomachs. In the late pregnancy, this situation will be more obvious. At this time, the level of male hormones secreted by male babies will increase, which will have a more obvious impact on the endocrine of pregnant mothers.

2. Skin condition

During pregnancy, if you find that your skin condition is obviously worse, such as rough skin, enlarged pores, acne, etc., apart from the factors of improper diet, it is likely to be a sign that you are pregnant with a baby boy. Because the male hormones secreted by male babies may affect the endocrine status of pregnant mothers, thus affecting the skin condition.

3. Changes in taste

There has always been a saying among the people that sour children are spicy women, and some people say that pregnant boys like meat and pregnant girls like vegetables. At present, these statements have not found obvious scientific truth. Some pregnant mothers do have this performance, but others don't. In addition to personal taste preference, if you like to eat sour and meat during pregnancy, it may also be a sign of being pregnant with a boy.

4. Eat more

Boys need more energy and substances than girls, on the one hand, because boys need more substances for their growth and development, on the other hand, because boys are generally more active than girls and need to consume more nutrients. Therefore, in the case of similar weight, pregnant mothers with male babies will eat more than pregnant mothers with female babies.

5. Fetal heart movement

If the fetal heart beat is strong, but the fetal heart rate is relatively slow and the fetal movement is active, it is likely to be a boy. If the fetal heart beat is slightly weaker, but the fetal heart rate is relatively faster, around 15, and the fetal movement is not so active, it is likely to be a girl.

6. Pregnancy reaction

Some pregnant mothers said that pregnant girls are more likely to have severe pregnancy reaction in the early stage of pregnancy, especially morning sickness. When pregnant with a boy, the pregnancy reaction is relatively mild, and morning sickness is not so obvious.

7. pregnancy line

Many women are president pregnancy line when they are pregnant. If you find that your pregnancy line is thin and long, and reaches your chest, you may be pregnant with a boy.

8. Frequent defecation

If you urinate regularly before pregnancy, but after pregnancy, you will become more frequent, and you may be pregnant with a boy.

9. B-ultrasound data

According to the experience of many pregnant mothers, watching B-ultrasound data can also help to judge whether the fetus is male or female. If the gestational sac is long, it is likely to be a male baby. If the gestational sac is oval or round, it is likely to be a girl.

second, the difference between pregnant boys and pregnant girls

from a medical point of view, there is no difference in performance between pregnant boys and pregnant girls. If you want to know the sex of the fetus, the most accurate way is to identify it by the sex chromosome of the fetus, or to observe the external genitalia of the fetus by B-ultrasound to judge the sex. However, in China, the sex identification of the fetus is not allowed. So there is no scientific way to judge the sex of the fetus.
