Labor???

So there is a possibility that this baby may come tonight or tomorrow, I have been in and out of the OB for a few days now on a medication to stop my contractions and the medication is now not working anymore so I have stopped taking it and and the contractions have gotten stronger and close all day and now they are really starting to hurt me and I have a lot of pressure, but the hospital that I go to is about 30min from my house so I don't want to drive up there to soon I am trying to wait until my water breaks or they get bad bad so I'll keep ya'll posted on what happens!
