Thanks Mel,

It's good to be armed with this info, I think, especially as I had threatened labour at 29 weeks with #3 (actually I have had hospital stays prematurely with all of mine!!), but this is feeling very different to what it felt like last time, so I will keep an eye on it. Might also see if the dr is willing to do an internal at my appt next week, just to make sure it's all still ok, or see what's going on ....
