My first two were inductions and my third was spontaneous so in that respect they were totally different.

With #1 I had prelabour for a few weeks before I delivered at 38+5. 3hr labour.
With #2 I was in early labour off and on from 20wks and 3cm from 33wks until I was induced at 37+6. 90min labour.
With #3 I had nothing except the odd bout of braxton hicks. It was quite boring lol I ended up having a bit of prelabour the day before he was born (30 March), then that night I went into early labour but it didnt establish until the day he was born (31 March) at 1pm and he was out by 3:01pm. 2hr labour.
