Different here too

DS1 41+5 weeks had a hospital appointment for post dates check up, had cervidil inserted and told it shouldn't bring on labour but ripen my cervix so it's favourable for induction in 2 days, went shopping, went home, cooked dinner all the usual stuff, sat down and at 9.30pm had a giant urge to clean. Started getting ready for bed at 10.30 and had my first contraction at 11pm. DS1 was born at 12.48am - 1 hr 48 min labour

DS2 38+5 weeks woke up from an amazing sleep, looked at the time. Bang on 7am. Then BAM first contraction. DS2 was born at 9.26am - 2 hr 26 min labour
