In case anyone's wondering, I'd thought I'd post a short update...

Well, I'm still waiting! (obviously)

It's now been over 5 days since I was told I was 5cm dilated. Weird!

I've just made an appointment with my OB for tomorrow morning - 1) because my DH is getting worried; and 2) because my OB is on holidays from later this week and I need to find out about / meet his locum ('cause I told him I'd rather have a different OB for the birth, than have to be induced for no reason other than to work around his holidays!).

I guess I'll also be able to find out if I'm any further dilated, which might be useful!
