I have a scant amount of some kind of vaginal and/or urine discharge throughout the day, not necessarily just at night. I think it's urine because of the odor, but I certainly can't control it! Haven't worried about it, although it is kind of annoying. My sister had this same problem with her pregnancy...she had to start wearing a daily light pad. Sigh.
I've been wearing a pantiliner because of all of the discharge and occasional drops of urine. I've also been doing my kegels religiously and that helps a bit. I guess this is just another one of the joys of pregnancy that no one tells you about!
