An occasional anger in the fifth month of pregnancy will not have too much effect. If you are in a state of anger for a long period of time, it may cause transient hypoxia of the fetus, and the fetus will be prone to crying and agitation after birth. When a woman is in the fifth month of pregnancy, the level of fetal development is relatively stable, and occasional anger will not affect fetal development. If a woman is frequently angry or has relatively large emotional changes, it may cause an increase in the release of hormones from the body, accelerated breathing and heartbeat, and accelerated blood flow, which increases oxygen consumption, thus leading to a relative decrease in the amount of blood normally supplied to the umbilical cord, affecting the blood supply to the umbilical cord, and resulting in a transient lack of oxygen to the fetus. In addition the fetus has the sense of hearing at 4 months, and at 6 months the fetus can hear all kinds of sounds in the outside world. When emotionally irritable and unstable during pregnancy, the fetus will be born easy to cry and agitated. It is recommended that women have some control over their emotions during pregnancy, and can increase the frequency of exercise to adjust the effect of their own hormone levels on the growth and development of the fetus. Pregnant women during pregnancy should pay attention to do a good job of prenatal checkups, actively listen to the advice of professional doctors to do a good job of comprehensive care and health care, pay attention to rest, at the same time should be relaxed, to avoid nervousness, anxiety, there is any discomfort should be timely to the hospital, by the doctor to clarify the diagnosis, and cooperate with the doctor to deal with the symptoms.
