oh, you'll know when your water is leaking, even slightly. Discharge is normal, to me anyway. Like Jaschem said, your body is simply getting ready. I'm 38 weeks and feeling alot of the pressure and i've started to lose a bit of the ' plug' . Your muscles too , down there, may be softening, if that's possible. So concentrate on your keigel excercises, holding those muschles, realease, and repeat. You'll be feeling alot of different things in the next few weeks, so if you have major concerns, tell your OB.
