LEEP discharge ...
is typically a blood-tinged watery discharge without odor. It also tends to decrease in volume over the next few days after the procedure.
If the discharge gets worse, or there is a new odor, it is not considered normal. Uterine cramping can occur after a LEEP for 1-2 days but a LEEP should not abdominal distension. Good luck and call the doctor who did your LEEP for further instructions.
