You should head to L&D, it sounds like you might be leaking fluid and that needs to be checked right away. When you add in the cramps I think you should get checked sooner rather than later. labor and delivery is there for this purpose, if you dr can't see you sooner or you want to get checke tonight L&D can Always see you.
Hope Friday is not too late!? Cos am freaking out already??? Hope nothing is gonna happen to my baby?
Fluid may have a light smell, and be a tent of yellow sometimes light brown. Sounds like normal discharge to me. But when in doubt call your OB / midwife, they will be able to give you the best advice & answers. I wouldn't run up to labor & delivery with out speaking to my Dr first. No point in being monitor for 2 hours just to be send home. Lol but good luck: -)
