During pregnancy, many expectant parents are curious about the gender of their baby. There are many methods for predicting boys and girls, but there is no scientific basis for their accuracy. Here is a brief analysis of the eight methods you mentioned, but please keep in mind that these methods are for fun and not an accurate way to establish the gender of your baby.
Look at the pregnant belly: Some people say that a pointed belly is a boy and a round belly is a girl. But in fact, the shape of the pregnant belly is affected by many factors, such as the mother\’s body shape, the position and size of the fetus, etc., and has no direct relationship with the gender of the fetus.
Look at the body shape: Some people think that after pregnancy, only the belly becomes fat, which is a boy, and those who are fat all over the body are girls. However, this statement also has no scientific basis. Everyone\’s physique and eating habits are different, so changes in body shape cannot accurately predict the gender of the fetus.
Look at the taste: \”Sour and spicy food\” is one of the most widely circulated rumors about giving birth to a boy or a girl. If a pregnant woman likes to eat sour food, she will give birth to a boy, and if she likes to eat spicy food, she will give birth to a girl. Moreover, pregnant women who are pregnant with boys have a huge appetite and eat their favorite foods. The speed and strength of fetal heart rate. It is generally believed that if the fetal heart rate is strong and slow, the fetus is more likely to be a boy; otherwise, it is a girl. However, changes in taste during pregnancy are more influenced by hormones and have nothing to do with the gender of the fetus.
Look at stretch marks: The shape and color of stretch marks are considered to be able to predict the gender of the fetus, but this also has no scientific basis. The formation of stretch marks is related to many factors, such as skin elasticity, weight gain during pregnancy, etc.
Look at the gestational sac: The shape of the gestational sac is thought to predict gender, but this is also unreliable. The shape and size of the gestational sac are affected by many factors, such as the development stage of the embryo, the shape and size of the uterus, etc.
Look at the placenta: The position or shape of the placenta is thought to be related to the gender of the fetus, but this again has no scientific basis. 
Look at the fetal heart rate: The rate of fetal heart rate cannot accurately predict the gender of the fetus. The change of fetal heart rate is restricted by various conditions, such as the activation state of the fetus and the mother\’s attitude.
Look at the skin: If the appearance of pregnant women becomes beautiful,If the skin becomes smoother, you may be pregnant with a girl; on the other hand, if the appearance becomes ugly, the skin becomes rough, or even the face is covered with acne and other symptoms, you may be pregnant with a boy. Changes in taste in pregnant women.
Generally speaking, this kind of folk method of predicting boys and girls lacks scientific proof and cannot be used as an accurate way to determine the gender of the fetus. The most reliable way is to have a medical test, such as an ultrasound or genetic test, but this method is generally only performed when medically necessary. It’s the same for boys and girls, the key is the child’s health and happiness. Therefore, expectant parents do not need to worry too much about the gender of the fetus, but should pay more attention to health care during pregnancy and the healthy development of the fetus.
