John Braxton Hicks

Braxton Hicks contractions, also known as false labour or practice contractions are sporadic uterine contractions that usually start around 6 weeks however are not usually felt until the second trimester or third trimester of pregnancy.

Symptoms
They should be infrequent, irregular, and painless. Hah...good joke. Painless??

Cause
Braxton Hicks contractions are a tightening of the uterine muscles for one to two minutes and is thought to be an aid to the body in its preparation for birth. Not all expectant mothers have these contractions. They are thought to be part of the process of effacement, the thinning of the cervix.

Worsening factors
Dehydration can make muscles spasm, bringing on a contraction, and is thought to be a factor in extended Braxton Hicks contractions. Adequate hydration can alleviate Braxton Hicks contractions.
Rhythmic breathing may alleviate the discomfort of Braxton Hicks contractions. Like "hee hee hee hoooo"? Aren't you just supposed to do that for the real deal?
Lying down on the left side can help ease the pain of contractions. Or, it could make them hurt worse.
A slight change in movement sometimes makes the contractions disappear.
A full bladder can sometimes trigger Braxton Hicks, so urination may end the contractions. Negative, Ghostwriter...didn't work.

History
Braxton Hicks are named after the English doctor who first described them. In 1872, John Braxton Hicks investigated the later stages of pregnancy and noted that many women felt contractions without being near birth. This process was usually painless but caused women confusion as to whether or not they were going into actual labor. It has since been found that Braxton Hicks' contractions are much less noticeable during exercise, whereas real contractions are not. Could someone please tell me how does a man determine that these contractions are painless?? And what would possess me to exercise while I'm uncomfortable??
