Clear urine means you are well hydrated, leak in your water bag would wet your underwear to the point you would use a pad to catch it, like a little poise thing. Yellow urine, tells how dehydrated your body is. Goggle it. As far as the cramps, time them, call at about 5 mins apart for over an hour, that I s typically when a doctor will want you to cone in, and be sure they are increasing with pain, and not just braxton hicks, or you are just wasting your own time.
Time your contractions for awhile.
If your water broke, you'd be leaking constantly or a big gush, not only when you try to pee.
I would call and tell them what is going on. They may have you come in or they may tell you to wait until contractions are closer together.
