What Are the Different Types of Contractions, and What Do They Mean?
As your pregnancy draws to a close, you might be obsessing about labor contractions. Find out more about the types of contractions you can expect, how they feel, and what they mean for labor and delivery.
No matter where you are in your pregnancy, you're probably thinking an awful lot about the end of it—labor, delivery, and that beautiful baby. And what's going to get you there? Contractions.
Consider contractions your body's way of helping nudge your baby out into the world. "The uterus surrounds the baby, and when the uterine muscles contract, that helps labor progress," says Bart Putterman, M.D., an OB-GYN at Texas Children's Pavilion for Women in Houston. The uterine contractions get your baby into position for birth and help them maneuver through the birth canal.
But having contractions before you're due doesn't necessarily mean that Baby has requested an early checkout from Hotel Utero. Here's what you need to know about the different types of contractions and what they mean.
Types of Contractions and What They Mean
Some contractions signal that you're in labor, while others simply mean that your uterus is preparing for delivery. Here's how to tell them apart.
You may start to feel a tightening and hardening of your stomach throughout your pregnancy; this signals that your body is preparing for labor and delivery. "The uterus is exercising for the grand finale," says Paul du Treil, M.D., director of maternal and child health at Touro Infirmary in New Orleans. These first disorganized twinges are a precursor to the real deal.
Causes of early contractions include stretching of the ligaments around the uterus, dehydration, constipation, and gas pains. If they're accompanied by spotting, bleeding, and/or abdominal pain, you need to see a doctor to rule out an ectopic pregnancy or a potential miscarriage.
Braxton Hicks Contractions
Starting in the second trimester, some women experience sporadic "false" contractions known as Braxton Hicks. They generally aren't painful, last anywhere from 30 seconds to 2 minutes, and happen randomly (although they can be trigged by things like exercise or intercourse.)
Braxton Hicks contractions signal that your uterus is preparing for delivery. Try calming the cramps by drinking plenty of water, taking a warm bath, emptying your bladder, and breathing rhythmically.
Before 37 weeks of pregnancy, contractions that come regularly (every 10 minutes or less) may signal preterm labor. Report any contractions to your doctor or midwife so she can determine what's happening.
If you have a normal, uncomplicated pregnancy, orgasms—with or without intercourse—don't increase the risk of premature labor. Likewise, sex during pregnancy isn't likely to trigger labor even as your due date approaches, but you may experience Braxton Hicks contractions or even light spotting afterward. These should subside in a couple of hours. If they're accompanied by any troubling symptoms (like bleeding, pain, vaginal discharge, or a decrease in fetal movements), contact your doctor or midwife.
True labor contractions might start out as an occasional, uncomfortable twinge of your stomach. They'll slowly build to something more, like really bad menstrual cramps or gas pains. As labor progresses, these contractions will become stronger, more intense, and closer together.
The easiest way to know if you're having true labor contractions is by doing a simple self-test. Lie down and place a hand on your uterus. If your entire uterus is hard during the cramping, it's probably a contraction. If it's hard in one place and soft in others, those are likely not contractions—it may just be the baby moving around.
True labor contractions can cause back pain, ranging from a dull aching or cramping that radiates towards your uterus to more severe discomfort in the lower back. If the pain is intense and remains mostly in your back, you are likely experiencing back labor.
Back labor is typically a result of the baby's position as it moves into the birth canal. Babies that present with their heads facing up (called occiput posterior) often place more pressure on the nerves in the mother's back, causing a heightened sensation of pain. But some laboring women simply feel the pressure of contractions more acutely in their backs, which may or may not subside as the labor progresses. Talk to your birthing staff about pain relief options—there are medicated and drug-free ways to reduce the pain of back labor.

How to Handle Labor Contractions
Once labor contractions begin, note how long they last and the length of time between them (measured from the beginning of one contraction to the beginning of the next). You're considered to be in active labor if you have regular contractions that last for about a minute and come more often than every five minutes.
Unless you're very uncomfortable during early contractions or you live far from the hospital or birthing center, your doctor or midwife may recommend staying home until active labor starts. "You may be able to go about your life when labor starts, but there's a time where the energy shifts, and you can't do anything other than labor," says Siobhan Kubesh, a certified midwife with OB-GYN North in Austin. That's usually when it's time to hit the hospital or birthing center.
If this is your first pregnancy, it might take a while for your body to get into the groove. Your entire labor will likely last for several hours—or even more than a day. Subsequent pregnancies may involve much shorter labor. "Second and third babies typically come a lot quicker," Dr. du Triel says. "The mother's body has done this before and remembers the process, so they can quickly progress to active labor."
