Clear watery discharge at 26 weeks pregnant?

I'm 26 weeks pregnant and have been noticing lots of extra vaginal discharge. Over the last week or so, its been clear and watery. It's not a huge gush, doesn't run down my leg or nothing but it feelslike a lot because sometimes I can feel it..uh...come out. It's generally odorless. Saturday I was noticing it, and when I got out of the tub I let out some clear very funny smelling liquid (also clear and watery). I couldn't place the smell. But it was so bad smelling from leaking onto my pj bottoms and undies I had to clean up and sleep in the buff (luckily I didn't leak). I figured maybe it was water from the jacuzzi tub (warm water! And short time) and maybe I peed alittle (ick) causing the smell. Since its been back to the normal amount clear watery and no odor. I have a doc appointment next Thursday but in the meantime should I be worried?
