Is it normal for a pregnant boy to have a hard stomach in the morning? What are the specific changes! The morning stiffness of a pregnant boy's stomach may be a normal phenomenon, but it may also be a symptom that needs attention. Before providing a more detailed explanation of this, let's first take a look at the relevant knowledge mentioned above.

1： Gender determination

The gender of humans is determined by the chromosomes carried by their parents. Women have two X chromosomes (XX), while men have one X chromosome and one Y chromosome (XY). The sex of the fertilized egg is determined at conception, which means that male sperm (Y chromosome) fertilized egg develops into a boy, while female sperm (X chromosome) fertilized egg develops into a girl.

2： Changes during fetal development

From conception onwards, the fetus undergoes a series of growth and development processes. In the early stages of pregnancy, the fetus will develop basic organ structures. In the second week of pregnancy, the embryo begins to form important organs such as the nervous system, circulatory system, and digestive system. By the fourth week of pregnancy, the fetus's spine, heart, and digestive system begin to develop. By the sixth week of pregnancy, the fetal head and limbs begin to form, and the fetal heart begins to beat. By the eighth week of pregnancy, the main organs of the fetus have already fully developed.

3： The relationship between fetal activity and abdominal stiffness

As the fetus continues to grow and develop, they begin to exhibit some movements and reactions. The activity of the fetus in the uterus will gradually increase, especially in the middle and late stages of pregnancy. The movements of these fetuses include beating soy sauce, kicking feet, rolling over, etc. These movements can usually be felt by touching the mother's belly. Sometimes, when the fetus moves or performs certain movements, the mother may feel her stomach become stiff.

4： Is it a normal phenomenon or a symptom that needs attention?

A stiff stomach in the early morning may be a normal phenomenon and is very common in the middle to late stages of pregnancy. This hardening may be caused by fetal activity in the uterus. The movement of the fetus can cause the uterus to contract, which can make the stomach feel stiff. In this situation, there is usually no need to worry excessively, as this is one of the normal manifestations of fetal healthy growth.

However, there are also cases where a stiff stomach may require attention. If the stomach becomes very tight and accompanied by pain or discomfort, it may be caused by uterine contractions or other problems. This may be a sign of premature birth and requires timely medical attention. In addition, if abdominal sclerosis is accompanied by other symptoms, such as reduced fetal movement, vaginal bleeding, rupture of amniotic fluid, etc., it is also necessary to consult a doctor in a timely manner.
