Pregnant women who are experiencing depression may think their symptoms are just a normal part of pregnancy. But in fact, the following signs may indicate depression: two or more weeks of depressed mood, decreased interest or pleasure in activities, change in appetite, change in sleep patterns, fatigue or loss of energy, difficulty concentrating, excessive feelings of worthlessness or guilt, thoughts of suicide, extreme restlessness and irritability.

Severe depression during pregnancy can interfere with women’s ability to eat properly, get enough rest, or receive prenatal care — all of which may contribute to premature and low birth-weight infants.
