I have low fluid - which was diagnosed at my 20 week scan. I'm not sure if I've had any leakages, although at one point the level went right back up to normal, then I was at work one day and stood up and had a trickle which soaked my pants and went down my legs..at the next scan my waters had gone right down again. Currently I'm being seen every 2 weeks for fluid measure and every 4 for growth scans.
