Water broke?

I'll be 38 weeks tomorrow and I think my water broke. I woke up this morning and when I stood up I got a very strong shooting pain from my lower abdomen to my vag. I then walked over to the rest room and peed. When I stood up and pulled my pants up I felt that they were wet. I checked and there was a big wet spot on them but it didn't smell like pee. I've had a few contractions but nothing strong. I'm still feeling some leaking but not much. I'm worried about going to the hospital too soon because I'm trying for a vbac and if I don't progress quick enough I'm worried they will push for a repeat csec. I don't know what to do. Any advice would be appreciated.
