At about 10pm my braxton hicks contractions started feeling a little 'different'. Nothing triggered it, I was lying on the couch! Ignored it and went to bed, woke up a couple of hours later as I was having regular contractions - bit hugely painful but uncomfortable enough to keep me up. They sloooowly increased over the next 12 hours, went to hospital at 4pm, DD born with the help of forceps at 8:30 the next day. She took her time!
