If your first baby was born early, when was the next one born?

[excited18]

My first, jumped ahead a week at the dating scan and then was born 2 weeks early (not induced, my waters broke). Based on my dates he was born at 37 weeks.

I'm now pregnant with my second and they have also jumped ahead a week at my scan.

Is this one likely to be early too?

DC1 - 11 days early.
DC2 - 5 days late.
