10 Early Signs of Preterm Labor With Twins Every Mom Should Know
One of the biggest concerns during a twin pregnancy is preterm labor.
While many twin pregnancies reach 36 to 38 weeks, twins are more likely to arrive earlier than singleton babies. Knowing the warning signs can help you seek care quickly if labor begins before 37 weeks.
Remember, not every symptom means you're in labor. The goal is to recognize changes and know when it's time to contact your healthcare provider.
Why Is Preterm Labor More Common With Twins?
Twin pregnancies place more pressure on the uterus and cervix as your babies grow.
Because of this, contractions and cervical changes may happen earlier than they do in singleton pregnancies. Your provider may monitor you more closely throughout the third trimester for signs of preterm labor.
1. Regular Contractions
Braxton Hicks contractions are common during pregnancy.
However, contractions that become regular, stronger, or closer together may be a sign of true labor.
If your contractions continue despite resting, drinking water, or changing positions, call your healthcare provider.
2. Pelvic Pressure
Many twin moms describe feeling like their babies have suddenly "dropped."
Increasing pelvic pressure or the sensation that the babies are pushing downward may be a sign your cervix is changing.
3. Low Back Pain
A constant, dull ache in your lower back that doesn't improve with rest may be another warning sign.
Sometimes back pain is one of the earliest symptoms of labor.
4. Menstrual-Like Cramps
Cramping that feels similar to a menstrual period, especially if it comes and goes regularly, shouldn't be ignored before 37 weeks.
5. Increased Vaginal Discharge
A sudden increase in discharge or a noticeable change in its color, consistency, or amount may indicate cervical changes.
If something seems different than usual, contact your provider.
6. Your Water Breaks
Water breaking doesn't always happen as it does in the movies.
Sometimes it's a large gush.
Other times it's a slow trickle that continues throughout the day.
If you think your water has broken, contact your healthcare provider or go to Labor and Delivery.
7. Spotting or Bleeding
Although light spotting can happen for several reasons during pregnancy, any vaginal bleeding should always be reported to your healthcare provider.
8. Diarrhea or an Upset Stomach
Some women notice diarrhea or stomach cramping shortly before labor begins.
When combined with other symptoms, it may be another clue that labor is starting.
9. Trust Your Instincts
Sometimes you simply know something has changed.
If you feel like something isn't right, trust yourself and call your healthcare team.
You know your body better than anyone else.
10. Cervical Changes
The only way to know whether your cervix is dilating or effacing is through an examination by your healthcare provider.
If you're experiencing signs of preterm labor, they may recommend evaluation in the office or Labor and Delivery.
When Should You Call Your Healthcare Provider?
Contact your provider immediately if you experience:
Regular contractions before 37 weeks
Leaking fluid
Vaginal bleeding
Severe pelvic pressure
Decreased fetal movement
Severe abdominal pain
Any symptom that concerns you
It's always better to call and hear, "Everything looks okay," than to stay home wondering.
💛 Twin Mom Tip
If you're unsure whether you're having contractions, start timing them. Write down when they begin, how long they last, and how far apart they are. Having that information ready can be very helpful when you call your provider.
