Braxton Hicks contractions

These sensations, which some women may experience as a strong pain, were discovered as typical symptoms of pregnancy by Dr. John Braxton Hicks and thus named after him. By observing women for many years, he noticed that the uterus muscles contract during pregnancy. The contractions, which last 30 to 60 seconds, are a normal part of a healthy pregnancy. Nevertheless not all pregnant women experience Braxton Hicks, though these start in the beginning of pregnancy. Usually they are noticed after the 20th week. They may increase in number and intensity as the pregnancy progresses. Changing your position or activity can help to relieve the discomfort. This can also provide an opportunity to practice your breathing as your due date approaches.
