Wrestling during pregnancy does not usually cause birthmarks in fetuses. Birthmarks are caused by hyperpigmentation or vascular abnormalities of the skin, and are not directly related to falling and touching your stomach.
Birthmarks are medically known as pigmented nevi, caused by hyperpigmentation or skin vascular abnormalities, and appear at birth or a few months after birth, and may fade or disappear as the baby grows.
In addition, when a pregnant woman wrestles, the fetus is protected by the abdominal wall, uterine wall, amniotic fluid, etc., which does not lead to pigmentation as well as fetal vascular abnormality, and the birthmark usually does not appear.
Although wrestling will not lead to birthmarks, but pregnant women wrestling is not good for the fetus, if there are symptoms of abdominal pain or vaginal bleeding after the fall, you should consult a doctor in time, under the guidance of the doctor for diagnosis and treatment.
