Hi Mecil

I had the same thing, can't remember exactly when but it would have been around 30 weeks. I did worry that it might be a leak but it only happened over a few days and then stopped. I tested whether it was a leak by putting on a pad and coughing (nothing happened), then by lying down for a while, getting up and seeing if anything had come out (it hadn't). I had read somewhere that this was one way to see if you had a leak. You should also be able to distinguish between urine and amniotic fluid by the smell (amniotic smells sweetish I believe) but this didn't help me much as I still couldn't tell what it was!

I'm sure someone else will post and give you some more info, but in the meantime if it's intermittent and not a large volume, chances are it's just some kind of fluid discharge.
