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.
One of the most reliable signs that you are carrying twins is the presence of multiple heartbeats. At around 12 weeks of pregnancy, your health care provider will be able to do a Doppler test, in which he may be able to distinguish two heartbeats.
