TMI.....TMI.....TMI....TMI...TMI.....TMI...TMI

I'm 36 weeks tomorrow and I've been feeling like I need to wipe in the vaginal area more than i normally would. Almost like I peed and had forgotten to wipe. Eveytime i get up i feel like i peed myself. Its constantly wet down there im soaking my draws and panty liners. I've been having period like cramps and there's so much pressure when I walk to the point where is too uncomfortable. Anyone else having this issue and if so is this something I should be concerned about?
