Water possibly broke?

Misti
Hey lady's im curious to find out when your water did break if anybody has had just an upper leakage and not the big gush everyone talks about. Im 38+5 weeks and think I might be leaking fluid but not sure. No painful contractions and only really feel it when im sitting or laying down. Weird thing is right before I feel it I feel whats feels like air bubbles then have the wetness. Can anyone relate or possibly recommend what to do to know for sure before rushing to hospital with out painful contractions.
