Just go to the doctors. It could be your water broke or you could be peeing on yourself. When I was pregnant, I thought my water broke but it turned out the baby was sitting on my bladder and I was actually just peeing on myself. I know, I was shocked and a bit embarrassed but the doctor said it happens all the time to lots of women.
If it is leaking you must immediately contact your gynecologist, do you feel the movement of the baby or not? You B.P. must be normal, I think it is an emergency must visit the doctor. Loss of amniotic fluid may put your baby in trouble and distress. SEE YOUR DOCTOR ASAP.
