a slow leak can be a problem if amniotic fluid falls below a certain level - a friend had to spend the last 10 weeks of her pg in hospital due to leaking waters, another delivered her bub at 25.5 weeks for same thing

it's better to be checked and reassured, than to leave it and find out it is a problem - my understanding is the swab test is really simple, and if it does show positive for amniotic fluid, they can scan you to make sure you still have significant enough fluid for the baby to stay safe.

i'm definitely one for playing it safe having seen the impact of these situations for my friends. i have had a fairly high amount of what i believe to be CM, but have appt tomorrow and will be getting it checked just in case....
