There is no necessary direct connection between a single pregnancy after a quarrel and fetal abortion. Excessive emotion in early pregnancy can cause miscarriage, and prolonged anger can lead to intrauterine hypoxia, which is certainly not good for the fetus and may lead to stillbirth in the long run. Some of them can induce fetal malformations, such as cleft lip, etc. The lack of oxygen can delay the development of the fetus’s mind, resulting in lower intelligence than normal, etc. However, it is unlikely that a simple quarrel will result in embryonic abortion. There is no unified research result on the causes of embryonic abortion, but there are many reasons that can lead to abortion, such as hormonal disorders, chromosomal abnormalities, exposure to harmful substances, cold and virus, trauma, endometrial inflammation, etc. Of course bad emotions such as anger and quarrels also have an effect on the development of the fetus. We cannot rule out the possibility of embryonic abortion and miscarriage. If the embryo stops after a fight once in a while, don’t get too upset, it may not be the cause, don’t have too much pressure on your mind. You should take good care of your life and keep a good mood. Eat a reasonable diet, less fast food and food that is not nutritious. Stay away from environmental pollution and exercise more during pregnancy preparation to strengthen your immune system. Take care of yourself for six months, go to the hospital for active medical checkups before preparing for pregnancy, and be ready to get pregnant again.
