See your doctor. These symptoms can only be adequately addressed by your doctor in real-time (face-to-face). Only after a thorogh evaluation, possibly including labs and other studies, can he/she determine what's wrong and what to do about it.
Normal discharge. You can see varying discharges during pregnancy, most of which have no particular significance. Check it out further if you are having other symptoms as well. If your water were to break you would see a steady amount of watery fluid.
