If you're carrying more than one baby, chances are good you'll deliver early. Twins are usually born around 36 weeks -- four weeks early. Triplets arrive at about 33 weeks, and quads often make their debut at 31 weeks.
It's usual for twins and multiples to be delivered before 38 weeks. Fewer than half of all twin pregnancies go beyond 37 weeks, and hardly any triplet pregnancies go beyond this stage. About 75% of triplets are born before 35 weeks.
