Oh you poor thing, I know how you feel! I have been getting a fair bit of discharge throughout this pregnancy, but a few weeks ago it turned very watery and I was just soaking my underwear... It is a horrible feeling, I know jus what you mean! I mentioned it to my GP, who whicked me off to my OB straight away, everyone was relieved to find out if wasn't my waters leaking which they had thought may have been the prob. Down side is it's not liely to get any better between now and having bubby Not a nice feeling at all.
My OB assures me for some women it is completely normal to have a lot of discharge throughout their pregnancy and it will go away post birth.... Thankgoodness for that!!! hehehe
Not too much longer and it will be all gone!

Sorry can't help with the wee prob, hope that gets better for you!
