Hi Mog
With ds, my waters broke at 33 weeks in middle of night - big shock, as you say it was a trickle and not the gush I had been led to expect and being 1st child and so early it took me about 10 minutes to cotton on what had happened - I woke dp up and said "I can't stop weeing!"
I spoke to the hospital and they said to come in, they monitored me but no contractions - I was told that 80% of people will go into labour within 48 hours when the waters break, so stayed in hospital for 3 days but no contractions.
I was scanned and monitored twice a day to check baby ok and they decided to send me home to see if I could get to 34 weeks so baby would have better survival rate, also gave me steroid injection to help develop ds's lungs.
They are concerned about the baby getting an infection once the waters have broken - saying that they let me continue about a week, then I got concerned I did not feel the baby moving as much so they brought me back in and were going to induce me once a cot available in special care. That night though I got mild contractions so I was induced to keep the labour going and eventually gave birth that night, ds 5lb 9oz so good size for 6 weeks early.
Although ok for 1st 30 mins he then got taken to SCBU for 10 days, on a ventilator for 3 days as he did have problems, possibly pneumonia, never able to identify exactly what infection he had - and no way of telling if this was due to waters breaking or his prematurity making him more susceptible.
I got mixed opinions on babys movements during this time - some said you would feel less movement as they cannot move around so easily as less water, the other view was I would feel more movements as there wan't the fluid to cushion the moves. So not much help there.....
I would see what your consultant or midwife has to say if you can speak to them, at 38 weeks though you are much further advanced than I was so some of this may not be applicable. Am I right in thinking that 38 weeks is not really considered to be early because of the 4 week window you have around your due date?
As I recall, once the waters break, you don't 'lose' all the water as your body carries on producing it. Gotta get those maternity pads out now though...
Oh, also told me not to have a bath (but showers okay)in case of passing on an infection.
Not sure if this is much help, but it is what happened with me,
hope everything goes okay, let us know how you get on. jemw
