Eating cold potatoes during pregnancy will not lead to miscarriage. Cold potatoes are a common vegetable and will not affect uterine contractions or the development of the fetus, and can be eaten during pregnancy. During pregnancy, the main diet is to eat as light as possible, do not eat food that is too heavy in taste, and do not eat more of anything. Foods with blood-activating properties should be eaten sparingly because they may induce miscarriage and bleeding. During pregnancy, prenatal checkups should be done on time, and proper activities and reasonable rest can promote the development of the fetus. If you have symptoms of preterm miscarriage such as stomach pain or redness during pregnancy, you must go to the hospital for a checkup and if necessary, you need to undergo fetal preservation treatment.
