Learn what the most common signs of labor are. And, find out how to tell the difference between real contractions and false alarms.
Real signs of labor
Once your baby is ready to be born, you will notice some bodily changes. Call your doctor right away if you have any symptoms of labor, even if your due date is weeks away. Six of the most common ones include:1. Rupture of membranes (your water breaks)
Many women know that the "water" breaking is one of the telltale signs of labor. But not all women are aware when this happens. The watery discharge is a result of the amniotic sac breaking. But, it can present as a flood, a trickle or even a slow drip. It could happen several hours before labor starts or not until you are well into labor. Call your doctor immediately if you think that your water has broken.2. Lightening
This is when the baby settles lower into your uterus, getting ready for birth. You may feel a clear change in the baby's position, or you may not notice any change at all. The term lightening is used because pressure is often taken off your diaphragm, making it easier for you to breathe (while increasing pressure on your pelvis).3. Changes in your cervix
In the weeks leading up to labor, your cervix will go through changes that you won't notice. As your due date draws closer, though, your doctor will see you more often and check your cervix at each appointment for:- Effacement. This is the thinning and stretching of the cervix. It is measured in percentages, with complete effacement being 100 percent.
- Dilation. This is the opening of the cervix. Dilation is measured in centimeters. Full dilation is 10 centimeters if you are at or near term.
4. Bloody show
During pregnancy, a thin layer of mucus forms over the opening to the cervix. During effacement and dilation, the "mucus plug" comes out. This shows up as a clear, pink or bloody discharge. This can appear any time in the days leading up to labor, once you start dilation. Call your doctor right away if there is any more blood than just a little blood-tinged mucous plug.5. Nesting
Some think this is a myth. Most women feel tired during the later stages of your pregnancy. But some women have a burst of energy close to labor. You may get an urge to cook, clean or finish other "to dos" before the baby comes. But keep in mind that labor is approaching, so it may be best to save that energy.6. Contractions
At the start of labor, your uterus tightens and releases in an effort to move the baby along through the birthing process. Contractions follow a regular pattern and increase in duration, intensity and frequency as labor progresses. Each lasts about 30 to 70 seconds and occurs every two to three minutes. The pain usually starts in your back and moves around to your front. Contractions can be very painful. They may mimic the pain of a bad back ache or menstrual cramps. But not all contractions signal "labor." Call your doctor right away if you have constant severe pain that does not get better between contractions as this pain may not be due to contractions.False labor
Braxton Hicks contractions are considered false because they do not lead to dilation of the cervix. They are also referred to as "practice contractions" because they help your body prepare for labor. Braxton Hicks contractions may start as early as the second trimester of pregnancy but are more common during the third trimester. Experts are not sure why they occur.It's common to mistake Braxton Hicks contractions for the real thing. Some women even make the trip to the hospital because they think birth is imminent. There are some key differences between real labor contractions and false ones. Braxton Hicks contractions:
- Do not follow a pattern
- In time, do not increase in duration, intensity or frequency
- Are unpredictable
- Are uncomfortable but not always painful
- May taper off or disappear when you move or change position
- Are usually only felt in your abdomen
