Keep an eye on it if cramps get stronger call L&D they will tell you what to do. In mean time drink water and lay down and rest, also you can do the pad test, put a pad in, lay down for a bit can't remember how long but let's say 30-60 mins stand up and see if more fluid comes out. Discharge can change though to water.
Your water shouldn't have a mucus texture it should be clear and watery with no smell. I have to wear a panty liner everyday because of the watery discharge. Cramps tho could be braxton Hicks. Are they consistent? Have you started timing them?
I just started to time them as they have been happening for over an hour. Been laying down on my side resting and drinking lots of water.
