Is it accurate to be pregnant and give birth to a boy? What are the symptoms of just being pregnant? Is it a boy?

For pregnant parents-to-be, they are very curious about everything about the fetus, especially some parents who seriously prefer sons to daughters. Most of them want to know the sex of the fetus as soon as possible. So, what is the reaction of the newly pregnant boy? What are the early pregnancy symptoms that are easy to give birth to boys? When will the sex of the fetus be known?

In fact, the heart rate of girls is higher than that of boys, which is only at birth. When they are both fetuses, there is no difference in the heart rate between male and female fetuses. When a pregnant mother listens to the fetal heart, she will actually feel the change. However, the heart rate only changes with the change of gestational age. Generally speaking, in the fifth week of pregnancy, the fetal heart rate is close to the mother's heart rate, that is, 80~85 beats/min. Then the heart rate gradually accelerated to 170~200 beats/min during the ninth week of pregnancy. In the second trimester, it gradually slowed down to 120~ 160 beats/min.

Frequent fetal movements in the third trimester, that is, fetal movements greater than or equal to 30 times/12 hours or greater than or equal to 4 times/hour, are also normal. At this time, expectant mothers need not worry too much. In fact, normal pregnant women should start conscious fetal movement at the 20 th week of pregnancy. With the increase of gestational age, fetal movement will gradually increase, especially in 32-34 weeks of pregnancy, but it should be noted that fetal movement will gradually decrease after 38 weeks of pregnancy. Due to the individual differences of fetuses, some fetuses can move about 100 times in 12 hours, but less than 20 times means that the fetus has intrauterine hypoxia.

It is very popular among the people to infer the sex of the fetus according to the frequency of fetal movement. Fetal movements in the third trimester frequently reflect that the fetus is male, but there is no scientific basis to show that there is a direct relationship between them. Therefore, frequent fetal movements in the third trimester have nothing to do with the sex of the fetus. Frequent fetal movements in the third trimester, as long as it is within the normal range, there is no problem. If it is too frequent, you need to consult the hospital in time.

How to check the sex after one month's pregnancy? Is there any basis for the American fetal sex test cup? The principle of using the test cup introduced online is similar to that of urine analysis. It uses the principle that urine reacts with chemicals for the first time in the morning, because alcohol is needed, that is, the acidity and alkalinity of urine react with alcohol, thus showing the sex of pregnant women and babies.

The earliest test period is 10 weeks of pregnancy or 6 weeks of menopause, which is a simple test that can provide results quickly. You only need 10 minute to observe the color in the Li Yide fetal sex test cup, and you can know the result. Green is a boy and orange is a girl.

The Old Yellow Calendar Table of Boys and Girls is what we often call the Picture of Boys and Girls in the Qing Palace. For thousands of years, people have calculated boys and girls according to this prediction table. According to the Table of Boys and Girls Born in the Old Yellow Calendar, we can know whether the baby is a boy or a girl by corresponding to the age (nominal age) and pregnancy month of the pregnant woman. Now, let's see what the old almanac looks like for boys and girls.

In 20 17 years, the row of boys and girls in the old yellow calendar indicates the month when a woman is pregnant, calculated by the lunar calendar; The columns in the table indicate the imaginary age of women's age. This table has no scientific basis and is for reference only.

In short, under normal use, it generally does not affect the fetus. The sound radiation dose of fetal heart rate is far below the requirements of safety indicators, but listening to fetal heart rate too much and too frequently will increase the unnecessary psychological burden of pregnant women to a certain extent, thus affecting the health of the fetus.
