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.
Twins Come Early. Another difference between a twin pregnancy and a singleton pregnancy is that the babies tend to arrive very early. Full term for a singleton pregnancy is 40 weeks. If you carry twins to 40 weeks, bless you. It is not an easy task. Most twins never make it that far. Most twins arrive around 36 weeks.
