Braxton Hicks contractions are irregular, non-rhythmic uterine contractions that occur in the late stages of pregnancy. They usually occur between 20 and 30 minutes before the birthing time. They are usually brief (lasting around a minute) and barely perceptible. Braxton Hicks contractions are named afte
r the doctor who first described them, John Braxton Hicks.
There are three types of Braxton Hicks contractions:
Tonic Contractions: Usually last over 30 seconds, they're the longest of all preterm prelabor signals and can cause discomfort.
Atonic Contractions: Brief and painless, these contractions usually last less than 10 seconds.
Mixed Tension Contractions: A combination of both types of contractions, they may feel as if you're going to start "giving birth" right now
The exact cause of Braxton Hicks contractions is unknown, but they are believed to be caused by a combination of anxiety, stress, and excitement. They may also be a sign of labor progressing. However, it's important not to confuse this with real or true labor pains - if you do experience any cramps or pain that's different from your usual Braxton Hicks contractions, call your doctor right away.
Braxton Hicks contractions usually start around the fourth month of pregnancy, but they can occur at any time. They can even start during early labor. Generally speaking though -- although there really isn't much science behind this -- people sometimes notice them when their cervix starts expanding slightly ("effacing").
Braxton Hicks contractions usually last for around a minute, but they can occasionally last up to 30 minutes.
These irregular uterine contractions, otherwise known as Braxton Hicks contractions, can start as early as the 4th month of pregnancy and are usually brief, lasting around a minute.
Usually no symptoms come with brawny uterus contraction because these small spasms have nothing that might bring on typical abdominal pain. However, some people feel a mild tingling or pressure sensation shortly before and during the contraction. You could describe it like having indigestion just before leaving work--except its worse! The cramps go away pretty much as quickly as they came. If they continue beyond a few minutes, it might be a sign that labor is starting.
If you experience any unusual cramps or pain that's different from your usual Braxton Hicks contractions, call your doctor. Otherwise, just relax and enjoy them! They're a normal part of pregnancy and usually don't cause any problems. Although they might vary in frequency, intensity, and duration from woman to woman, you're likely to experience them at some point during your pregnancy.
