Preterm (Early) Labor
Most pregnancies last 40 weeks. If you go into labor between 20 and 37
weeks of your pregnancy, we call it preterm labor.
Call OB Triage at 272-2460 if:
you have any signs of preterm labor for more than one hour
(see below for the signs of preterm labor).
you have any fluid or blood leaking from your vagina.
It may be possible to prevent a preterm birth by getting care early!
What Are The Signs of Preterm Labor?
4 or more contractions in an hour.
o It is normal to have some contractions of your uterus.
They can happen when you change positions, such as from
sitting to lying down.
o If you have 4 or more contractions in an hour, this is a sign of
preterm labor. Contractions that come this often can cause
your cervix to open up and the baby might come early.
A low dull back ache below your waistline. The ache might come
and go or it might be constant.
o Remember, low back pain is often a common and normal
part of pregnancy as the baby grows.
o In preterm labor, back pain usually changes suddenly. It is
usually strong, and comes and goes.
Discharge (fluid) coming from your vagina that is new or different
from normal.
o An increase in vaginal discharge is normal in pregnancy.
o In preterm labor, the change is often sudden, and might be
watery, mucusy, or bloody like a period.
How Do I Know If
I’m Having
Contractions?
Lie down. Put your
fingertips on the top of
your uterus.
If your uterus is
contracting, you will feel
your abdomen get tight or
hard during the
contraction. Then you’ll
feel it relax or soften when
the contraction is over.
Preterm contractions may
or may not be painful.

Cramps (like when you have your period) in the lower belly. The
cramps might come and go or they might be constant. You may have
diarrhea or you might not.
Pressure in your pelvis that changes suddenly.
o Pressure in your pelvis can be normal as the baby gets bigger.
o In preterm labor it might feel like your baby is pushing down
or the pressure might come and go. It usually happens along
with some of the other signs that are listed on the first page.
Is Preterm Labor Dangerous?
When someone has preterm labor contractions, their uterus tightens and
their cervix may open earlier than normal. This can cause an early birth.
If a baby is born early, it can have problems breathing, eating, and keeping
warm. That’s why it is important to watch for signs of preterm labor.
What Should I Do If I’m Having Preterm Labor?
Lie down on your side. Place a pillow at your back for support.
Don’t lie flat on your back, but don’t turn too far forward on your
side either.
o Lying flat on your back might cause the contractions to
happen more often.
o If you lie too far forward you might not be able to feel
the contractions.
Drink several large glasses of water and pee often. Sometimes
being dehydrated can cause contractions.
Try taking a warm bath. Sometimes this can relax your muscles so
your contractions slow down or stop.
Track your contractions for 1 hour.
o Count the number of minutes from the start of one
contraction to the start of the next. That will tell you how
often they are occurring.
o If you have more than 4 contractions in 1 hour, this is a sign
of preterm labor. Call OB Triage at 272-2460.
Did you know?
Some people have more
risk of having preterm
laborfor example, if
you are having twins or if
you have had a preterm
birth in the past.
Ask your provider if you
have a higher chance of
having preterm labor.
