It could be a little bladder leakage which is not uncommon late in pregnancy. It could also be leakage of amniotic fluid. Your water can break without significant progress in dilation or effacement or even contractions. It's also been a few days since you've seen your doctor, so a lot can change in that time. you should call your doctor tomorrow and just alert them to your symptoms. They may have you go to labor and delivery just to check if your water has broken and/or you've progessed since Monday.
