A bigger nose during pregnancy does not necessarily mean a son, and it is not possible to judge the birth of a son or daughter by the changes in the body, which is not based on science. After pregnancy, the body’s progesterone and estrogen levels will increase, pregnant women may have rough skin, pregnancy is a special stage, no active skin care, resulting in more obvious pores on the nose, from the sensory point of view, the nose will appear larger. Some pregnant women with severe edema may also exhibit a larger nose. The birth of a child depends on the type of sperm the man has. An egg-bound sperm containing an X chromosome will give birth to a daughter, and an egg-bound sperm containing a Y chromosome will give birth to a son. After pregnancy, do not judge the sex of the baby based on the symptoms and changes in your body, have regular checkups, and do not be overly concerned about the sex of the baby.
