Test Overview ...

Uterine contractions can be monitored externally, without inserting instruments into your uterus (external uterine monitoring). A belt is wrapped around your waist and attached to a machine called a tocodynamometer.

Contractions grow stronger and start coming every 3 to 5 minutes and for a duration of 45 to 60 seconds each. The cervix dilates from 3 to 8 centimeters and is effaced close to 100%.

Contractions can sometimes be brought on by light exercise or dehydration, so it is important to keep drinking plenty of fluids so that the uterus does not become over-irritated.

If contractions are accompanied by the loss of the mucous plug, or the breaking of water, it is a sign of true labor and you should contact your doctor immediately.

Post Delivery Contractions
by Cynthia Flynn, CNM, Ph.D.
Q. Is it true that the post delivery contractions become more intense with each subsequent birth/delivery?

When you start labor, contractions are irregular. Your membranes (bag of waters) may or may not break first. Once the contractions are regular and closse enough together, you will be able to go to the birthing center.

Waters breaking before contractions start
Sometimes, your waters break but you don't immediately go into labour. If you are more than 37 weeks pregnant, contractions should begin soon afterwards.

Women pregnant with multiples often experience tightenings or contractions, which can begin early in pregnancy (less than 20 weeks) and continue throughout.

Contractions are a normal part of all pregnancies. Most contractions do not thin and open the cervix. Rather, they are simply a brief stimulation of the uterine muscle.

Contractions. From 20 weeks onwards, many mums-to-be experience Braxton Hicks 'practice' contractions, when the womb seems to harden for a minute or so every 15 minutes.

Contractions and dilation (opening) of the cervix before 37 weeks of pregnancy are considered preterm, or premature, labor. A normal pregnancy lasts about 40 weeks after the first day of the last period (38 weeks after fertilization).

Contractions subside if you walk around or change position.
Contractions are not regular and don't increase in frequency or severity.
Signs of Real Labor include: ...

Contraction Stress Test - A test that measures the fetal heart rate in response to contractions.

Contraction Stress Test
If a non-stress test indicates a problem, this test is performed to check the baby's heart beat during contractions.

Contraction stress test (CST). This test is often recommended r if you have an abnormal non-stress test. Uterine contractions are produced either by stimulating the woman's nipples or via an intravenous administration of pitocin.

Contraction Stress Test
Why Is This Test Performed?
This test stimulates the uterus with pitocin, a synthetic form of oxytocin (a hormone secreted during childbirth), to determine the effect of contractions on fetal heart rate.

Contractions vary in each woman and at different stages of labour. In my experience as an obstetrician, there are painless contractions—I can feel tightenings, but the woman is not even aware she is contracting.

Contraction
Almost always refers to the contracting of the muscles of the uterus during labor. The uterus contracts in an effort to expel the fetus into and out of the birth canal.

Uterine contractions - During the birthing process, a woman's uterus tightens, or contracts. Contractions can be strong and regular (meaning that they can happen every 5 minutes, every 3 minutes, and so on) during labor until the baby is delivered.

False labor contractions are irregular and can be very painful. These contractions may be felt in various parts of your body (back, lower abdomen, pelvis).

Just having contractions does not mean pre-term labor. Contractions have to be organized enough to cause a net vector force outward, causing thinning and dilation of the cervix (same definition of real labor).

Fourth stage: Recovery. Feelings range from exhaustion to exhilaration!

Braxton-Hicks Contractions
Episodes of tightening of the uterine muscles are called Braxton-Hicks contractions. Although these contractions start very early in pregnancy, most women do not really notice them until the second half of their pregnancy.
