Water Breakage??

Brianna • FTM-June.04.2016, i love you son👑💙🚘
Im 38w6d, i'll be 39 weeks tomorrow. I know its not a guarantee that my water will break, so for the women whos water has broken...is there a pressure i will feel before it happens, or anything hinting that my water will break?? Or is it just a spontaneous burst?
