A due date is an estimate of when your baby may be born. It's normal for babies to be born from three weeks before to 10 days after the due date. Most babies are born between 37 and 42 weeks. Although it probably feels like the day will never come, you will go into labor.
Each labor experience is different and labor can start many different ways. It may start with your water breaking. Or, you may have a daylong backache that turns into contractions.
Your labor may start with contractions that have a pattern of lasting 45 to 60 seconds and coming every five minutes. Or, they may start 20 minutes apart and last 30 seconds.
The chart below explains some of the signs of early labor.
Vague, nagging backache causing restlessness and a need to keep changing positions.
This is different from the backache of pregnancy; contractions may be the cause.
Several soft bowel movements, sometimes with a 'sick' feeling in your stomach.
This is probably from an increase of hormones called prostaglandins, which soften the cervix.
Cramps that feel like menstrual cramps; the discomfort may go into the thighs.
This may be caused by prostaglandins and early contractions.
Unusual burst of energy, the 'nesting' urge.
The ensures you will have the energy for labor. Avoid starting a large project.
Slippery mucus discharge from the vagina that is tinged with pink or red blood; called 'bloody show'.
This is caused by the opening of the cervix. This is different from the brownish discharge that can occur after a pelvic exam or sex.
Contractions that do not become longer, stronger, and closer together (are nonprogressing).
These contractions are softening and thinning the cervix. This needs to happen before the cervix can dialate (open).
Fluid leaking from the vagina that can't be controlled like the flow of urine; called 'ruptured of membranes.
The amniotic sac is leaking fluid from a small tear. Contractions may start after this. Call your health care provier even if your contractions have not yet started. Only about 10 percent of labors begin this way.
Contractions that become longer, stronger and closer together over time (are progressing); felt in the abdomen and/or back.
This is a sign that the contractions are thinning and opening your cervix. It is difficult to distract yourself during these contractions.
A gush of fluid from the vagina. (There may be the sound of a pop when the membranes break. This is another form of "rupture of membranes".)
You may soon start having contraction that get longer, stronger, and closer together. Call your health care provider or hospital right away.
