PRE-LABOUR OR EARLY LABOUR?

Katie has been in pre-labour for about 24/24.  She phones and asks you to come over as her contractions are becoming more regular and she feels she may want to go to hospital soon.

Emily phones you at 2.30a.m. to let you know she is in labour and would like you to come over to her place.  She has been labouring at home for about 6hrs.  She is 41/40 and is booked into a Birth Centre.
