Most common week to go into labor

A full-term pregnancy is a pregnancy that lasts from 39 to 40 weeks.

Is it safe to deliver at 37 weeks

Each week of gestation is crucial for your baby's health and development. Moreover, conclusive research shows that birthing a baby before 39 weeks (and at or after 41 weeks) puts them at higher risk for a range of health and developmental problems.

"The evidence is so compelling that a growing number of American hospitals are launching programs to help prevent elective deliveries before 39 weeks of gestation," says Diane Ashton, MD, MPH, deputy medical director of the March of Dimes.

Here's everything you need to know about full-term pregnancies, from how many weeks a full-time pregnancy is, and why it matters.

According to the American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine, a full-term pregnancy spans between 39 weeks, 0 days, and 40 weeks, 6 days.
