On the TV sitcoms, the pregnant woman always grabs her big belly with a look of wide-eyed surprise and announces, “It’s time.” Unfortunately, labor doesn’t usually come on like that. You might spend a lot of time this month timing contractions, grabbing your suitcase, and then stopping short, realizing the contractions have stopped—false labor! False labor feels just like the real thing. That’s why thousands of pregnant women who rush to the hospital are sent home again to wait just a little longer. This is embarrassing, naturally (especially if you’ve woken your spouse, your parents, and your physician to announce the news), but it’s nothing new. When contractions start you can tell, usually, that real labor has not begun if you answer “yes” to these four questions:

Do the contractions stay the same in intensity (not getting worse)? Do the contractions come in uneven intervals (two minutes apart, then seven minutes apart, then four minutes apart, for example)? Is the pain in your lower abdomen rather than in your lower back? Do the contractions stop when you move around or change position?

If you’re saying “yes,” you’re not in real labor yet. When real labor contractions begin, you will find that you cannot walk or talk through them. That’s a good time to start packing.
