During pregnancy, if anger is too severe, it can lead to vasoconstriction and spasms, which can trigger uterine contractions and may cause signs of miscarriage or preterm labor, or cause abruption of the placenta which can lead to the possibility of bleeding. If you are constantly angry, depressed, depressed or irritable during pregnancy, this will also affect the growth and development of the fetus. Especially in the first trimester, if you get angry a lot, it may affect the growth of the fetus and lead to malformation of the fetus. In the middle of pregnancy, if you are often angry, it may affect the fetus’ neurological and intellectual problems, which may cause the baby to be unresponsive after birth, or it may not be able to communicate or communicate with people normally, or the baby may cry a lot after birth and sleep poorly at night. Therefore, during pregnancy, you should try to keep your mood relaxed and not to have too much stress.
