While excessive stress isn't good for your overall health, there's no evidence that stress results in miscarriage. About 10 to 20 percent of known pregnancies end in miscarriage.

Is getting upset bad for pregnancy?

High levels of stress that continue for a long time may cause health problems, like high blood pressure and heart disease. During pregnancy, stress can increase the chances of having a premature baby (born before 37 weeks of pregnancy) or a low-birthweight baby (weighing less than 5 pounds, 8 ounces).

Can negative emotions cause miscarriage?

Negative emotions and life events increase the risk of women's missed miscarriage, and the high educational level, good health status before pregnancy and the initiative to obtain the knowledge of prenatal and postnatal care reduce the risk of women's missed miscarriage.
