Thanks for your responses. Unfortunately I feel no less anxious about things. I think I'm destined to have another prem. From what I've heard from a few others and seems to be the pattern from you guys is that if there's no reason for the prem (eg PE) then you tend to go early again.

Like I said before there was no reason for my labour and what's more I had no idea it was coming. The scan 48hrs before DS's arrival gave absolutely no hint. I hadn't even had any braxton hicks. I didn't even know I was in labour for most of it - grand total from the first twinge to delivery was 3.5hrs. When I arrived at hosp I was fully dilated and they could see DS's head. (My water had broken at home but it was such a small amount I hadn't really realized what had happened.)

So I'm worried cos I don't think that even with close monitoring there would even be a clue I was about to deliver if things went the same way 2nd time around. Scary......
