The closer you get to giving birth, the more you may start to feel contractions, said Patricia Grade, MD, an independent member of the HonorHealth medical staff. These early contractions are called Braxton Hicks or false labor. Although they may help thin the cervix and are an important part of preparing your body for childbirth, they don't cause you to dilate or mean that you're actually in labor.
Dr. Grade answers commonly asked questions about Braxton Hicks contractions:
Q. What do Braxton Hicks contractions feel like?
A: Beginning as early as your second trimester, you might have a sensation similar to mild menstrual cramps. You feel a tightening or squeezing sensation that's not overly painful. Braxton Hicks contractions may happen more frequently as you enter your third trimester.
Unlike labor contractions, Braxton Hicks don't come at regular intervals or increase in intensity. If you walk or change position, they might go away. You may find they come at the end of a busy day, so try to rest and see if they subside.
Q. How can I tell if it's false labor or the real thing?
A: Time the contractions to see if they're coming closer together. Labor contractions last about 30 to 60 seconds. As time goes on, they come closer together, last longer, get stronger and are more painful.
Braxton Hicks are usually in the front of your abdomen. Real labor contractions tend to start in your lower back and work their way around to your belly – or they may move in the other direction, front to back.
Real contractions might start in the 37th week — anything earlier would be considered pre-term labor.
Q. When should I call my OB?
A: When in doubt, call. Your OB will ask you many questions (especially how close together the contractions are) and will give you further instructions. Always call if you:
- Have had strong contractions, five minutes apart for an hour
- Detect a noticeable change in your baby's movement
- Experience vaginal bleeding or an increase in vaginal discharges
- Feel that your water has broken
