Intervals that are too brief -- as well as those that are too long -- aren't desirable, research suggests.

The researchers looked at the intervals between pregnancies and the outcomes for those pregnancies. The study, led by Dr. Emily DeFranco, a clinical fellow in maternal-fetal medicine and a staff member at Washington University's Center for Preterm Birth Research, was published recently in the American Journal of Obstetrics and Gynecology.
Among the findings, according to DeFranco:
"Wait a minimum of 12 months before becoming pregnant again," DeFranco advised. That's to say, let 12 months or more go by after delivery before you start trying again to become pregnant. That advice is especially crucial for women who have already had a preterm birth, which raises the preterm risk in subsequent pregnancies, she said.
