35 weeks today with lovely DC4 
DC1 due date - long and hard old labour. 26 hours in total.
DC2 induced due to pre-e at around 39+4? 12 hour easy ish labour.
DC3 due date and labour was an absolute breeze. On off contractions all day then once it kicked off properly I think recorded active labour was 30 minutes!
What were your 4th births like?
I’m also convinced this one will be early, regular BH, he was 3/5 engaged last week. I feel very low and heavy.
