Thanks girls for the replies! Prelabour went for a full week and then on Thursday night my water broke at midnight. Contractions started at 2.30 and ds2 was born 40 mins later!
So if anyone else is reading this in the future my third labour was a long week and a bit of prelabour with things stopping and starting then once it got going he only took 40mins to arrive and that was me only pushing once for the head and once for the shoulders :-) went from 4cm at 2.30 to the birth so quickly!!
So I missed the induction by 3hrs, what a clever boy!!
