What happens when labor begins?
As labor begins, the cervix opens (dilates). The uterus, which contains muscle, contracts at regular intervals. When it contracts, the abdomen becomes hard. Between the contractions, the uterus relaxes and becomes soft. Up to the start of labor and during early labor, the baby will continue to move.
Certain changes also may signal that labor is beginning. You may or may not notice some of them before labor begins:
|Signs That You Are Approaching Labor|
|Sign||What It is||When It Happens|
|Feeling as if the baby has dropped lower||Lightening. This is known as the “baby dropping.” The baby’s head has settled deep into your pelvis.||From a few weeks to a few hours before labor begins|
|Increase in vaginal discharge (clear, pink, or slightly bloody)||Show. A thick mucus plug has accumulated at the cervix during pregnancy. When the cervix begins to dilate, the plug is pushed into the vagina.||Several days before labor begins or at the onset of labor|
What is false labor?
Your uterus may contract off and on before “true” labor begins. These irregular contractions are called false labor or Braxton Hicks contractions. They are normal but can be painful at times. You might notice them more at the end of the day.
How can I tell the difference between true labor and false labor?
Usually, false labor contractions are less regular and not as strong as true labor. Sometimes the only way to tell the difference is by having a vaginal exam to look for changes in your cervix that signal the onset of labor.
One good way to tell the difference is to time the contractions. Note how long it is from the start of one contraction to the start of the next one. Keep a record for an hour. It may be hard to time labor pains accurately if the contractions are slight. Listed as follows are some differences between true labor and false labor:
|Differences Between False Labor and True Labor|
|Type of Change||False Labor||True Labor|
|Timing of contractions||Often are irregular and do not get closer together (called Braxton Hicks contractions)||Come at regular intervals and, as time goes on, get closer together. Each lasts about 30–70 seconds.|
|Change with movement||Contractions may stop when you walk or rest, or may even stop with a change of position||Contractions continue, despite movement|
|Strength of contractions||Usually weak and do not get much stronger (may be strong and then weak)||Increase in strength steadily|
|Pain of contractions||Usually felt only in the front||Usually starts in the back and moves to the front|
