What are Braxton Hicks contractions? What are true or real labor contractions?
Braxton Hicks contractions or "false labor," are irregular contractions that occur during the third trimester of pregnancy, or possibly in the second trimester. Braxton Hicks contractions usually are milder than those of real labor are, and they do not occur at regular intervals.
What do Braxton Hicks vs. real contractions feel like?
- Braxton Hicks contractions do not occur at regular time intervals, and they can occur at any time of day. However, many pregnant women report that they can feel Braxton Hicks contractions at night when the bladder is full, and during exercise or sex. Braxton Hicks contractions may not be painful, particularly when they begin earlier in pregnancy.
- True labor contractions during childbirth usually get closer together, become stronger, and happen at intervals that become closer together. Many women often describe the pain of real labor contractions as occurring in a wave-like fashion.
How can I tell the difference between Braxton Hicks vs. true labor?
- Some pregnant women experience Braxton Hicks (false labor) contractions during the second trimester.
- When this occurs, the contractions do not come in regular intervals, and most women do not notice them.
- False labor contractions do not worsen over time and do not occur closer together. They may even lessen or go away when you move or change body positions.
- Braxton Hicks contractions may cause an uncomfortable tightening sensation but usually are not as painful as the real thing, or true labor contractions. Sometimes women who are experiencing Braxton-Hicks contractions believe that they represent real labor and experience a “false alarm” due to these symptoms.
- True labor or real labor contractions usually begin after the 37th week of pregnancy, except in the case of preterm or early labor.
- They are a sign that labor is starting, they occur at regular time intervals, and become stronger (more intense and painful), and closer together over time.
- Labor contractions and pain are most likely to occur close to your due date when true labor starts in preparation for the birth of your baby.
- You also may have other signs of labor, such as your water breaking (leaking amniotic fluid), the passing of the vaginal mucus plug, and/or "bloody show," when the mucus plug is blood-tinged.
How long do Braxton Hicks last? How long do real labor contractions last?
- Braxton Hicks contractions can vary in length, from less than 30 seconds to up to 2 minutes or more.
- Labor contractions usually last from 30 to 90 seconds.
When should I call my doctor, doula, or midwife if I think I may be in labor?
Before you are 37 weeks pregnant you should contact your care provider, obstetrician, or go to the hospital if you have labor contractions that are becoming more frequent (every 10 minutes or sooner) and painful. You should also seek medical assistance if you have abdominal pain, low back pain, cramping, a feeling of pressure in the pelvis or lower abdomen, vaginal bleeding, or a change in vaginal discharge.
After the 37th week, your healthcare team will advise you when you should call them or go to the hospital. With true labor, the contractions will happen regularly and become stronger, lasting about 30 to 90 seconds, and do not go away. Always contact your obstetrician or midwife if your water breaks, you have vaginal bleeding, are experiencing severe pain, or have any change in your symptoms that is concerning.
