Overall, women who became pregnant within six months of miscarrying had better outcomes and a lower risk of complications than their counterparts who waited longer to conceive after a miscarriage.

Women who waited two years to conceive after their miscarriage had a higher risk for potentially life-threatening ectopic pregnancy (when the fertilized egg has implanted outside the uterus, usually in the fallopian tubes) and/or pregnancy termination than women who conceived earlier. These women were also more likely to deliver via cesarean section or give birth to premature or low-birth-weight babies than women who became pregnant within six months after their miscarriage, the study shows.
