Should I be concerned?

So this morning after having a shower while drying off I had what I thought was a little "wee"...something I have had happen before. Well it happened a few seconds after again, was certainly not a gush of fluid but definitely noticeable. What worried me is that it's clear, water like and had  no odor. For a good two hours after I was VERY wet. It's subsided now but I did experience some light period like cramping a little while after. I'm 27 + 5 and the doctor aren't open today, so I'm not sure if I should be concerned or whether watery cm is something that's common in the third trimester, as well as light period like cramping?
