Very annoying - I have spent the past 2 nights awake with contractions coming between every 6 - 12 mins. Each time the session lasts for about 5 hours and then they go off! I have then spent the days with very painful contractions but at various times of the day with no pattern!! Has anybody else had this? This is child number 3 and I remember a similar experience with number 1 but had hoped this one would have been quicker! Oh well!
