ok, this really is TMI for you but i am 38 weeks pg with dc2 (dc1 is out with grandparents!) and dh and i were just engaging in some hopefully labour-inducing sex, when suddenly there seemed to be an awful lot of fluid on the bedsheets - i guess probably it was only half a glass-a glass worth of clear liquid but i am pretty sure i wasn't weeing myself - but would i know if i was weeing myself? And wouldn't there be more fluid if it was my waters??
