A history of traumatic or second trimester fetal loss increases the possibility of cervical injury and subsequent incompetence of the cervix, an often preventable cause of second trimester miscarriage. A history of premature delivery (newborn's weight <2500 g) or immature delivery (< 1000 g) increases the probability of recurrent early delivery. These patients require particularly close surveillance. A history of unexplained pregnancy loss in the third trimester should alert the clinician to undiagnosed medical problems in the mother, such as gestational diabetes or systemic lupus erythematosus. For women who have undergone previous cesarean section, there must be exact information about the reason for the procedure and the type of uterine incision used, so that it can be determined whether the patient is a candidate for a vaginal birth.
