1. Look at the gestational sac
The so-called gestational sac is the initial form of pregnancy and can only be seen in the early stage of pregnancy. At the 13th week of pregnancy, B-ultrasound can be used to predict the sex of the fetus by examining the shape of the gestational sac on the report and relevant data.
When it is found that the shape of the gestational sac on the examination report is round, it is likely that it is the female baby. When the length and width of the gestational sac are the same, the possibility of nubao will be greater.
2. Fetal heart rate
The so-called fetal heart rate is the fetal heart rate, you can buy a fetal heart rate detector for testing. When the fetal heart rate is found to be less than 140 times / min, it is possible to conceive a baby boy! On the contrary, if the baby's heart rate is measured to be more than 140 times / min, then the baby may be a little princess.
In addition, it should be noted that when the baby's heart rate is found to be lower than 120 or higher than 160, the pregnant mother should pay attention to it. For the sake of the health of the fetus, it is better to go to the hospital to consult a doctor.
3. Look at the skin
Because the sex of the baby the pregnant mother is pregnant with is different, the male hormone and the female hormone released in the body will also be different. When the pregnant mother is pregnant with Nanbao, due to the influence of Nanbao's androgen, the skin of the pregnant mother may be a little rough. On the contrary, if Baoma is pregnant with nubao, the skin of pregnant mother will become more lustrous and ruddy due to the influence of estrogen.
Therefore, through the skin condition of the pregnant mother, such as whether there is acne, pregnancy spots and other skin conditions, you can also roughly know the gender of the child in the pregnant mother's belly.
4. Look at the umbilical cord
Compared with men's, women's heads are smaller, so the umbilical cord will be longer. The longer the cord, the more likely it is to wrap around the neck. And according to experienced doctors, the probability of nubao's umbilical cord around the neck is far greater than that of nubao.
I always think that it's more likely to be around the neck when man Bao is naughty, but the real situation is just the opposite. So when we find that the navel of the fetus is relatively long or there is a phenomenon around the neck, the possibility of nubao is much greater!
Summary: the sex of the fetus has been determined since the sperm meets the egg. Whether it's a single-minded pursuit of children or a single-minded pursuit of a small padded jacket, it's not too hard to know whether the baby in the belly is a man or a woman. If you can infer from the above four points, it is better not to blindly believe in these standards. Finally, I hope pregnant mothers can have healthy and smart babies!
