My waters were lost in large volumes, i think with DD it would have been at least .5 litre. Ik flooded my bathroom floor, and that was the second of four big gushes at home. The one following I had gotten dressed, mat pad, thick trackies and soaked the lot. I seem to carry a lot of fluid!!! Definitely a good idea for the mucouses but depends on how you lose your waters as to whether or not it would be useful in that regard!
