I hate to say it Anna, but better safe than sorry. It sounds to me like you'd better head in to your OB/hospy tomorrow morning, and rest up in bed AMAP until you do.

The fact that it's stopped leaking is a good sign, maybe it's not your waters, but I would check to be on the safe side hun. Trust me, you REALLY want to put off going into labour early, if at all possible. Don't worry that they'll think you're being a stress-head, that's what they're there for, to get you and your bub through this safely.

Good luck sweets, let us know how you go.
