Braxton Hicks Contractions vs (True) Labour Contractions

Braxton Hicks contractions: 

1. are infrequent, usually happening no more than once or twice an hour, a few times a day
2. often stop if you change activity, so, walk around if you've been sitting, and vice versa
3. are usually irregular, and if they are regular they only stay that way for a short spell
4. do not last long, usually less than a minute
5. continue to be unpredictable and non-rhythmic
6. do not increase in intensity

Compared to Braxton Hicks contractions, labour contractions are usually:

1. noticeably longer
2. more regular
3. more frequent
4. more painful
5. keep on going, increasing in frequency, duration, and intensity as time goes on
