Labour signs? TMI warning

Hi mamas. FTM here due the 30th but having some symptoms that seemed odd. Been having ligament pain since 37 weeks in one side but it seems over the last few days to switch sides or increase in intensity. I have been having increased discharge thats sticky when I wipe (not my water, as I have been wearing pads just incase. I'd like to know if its possibly a mucus plug. Also feeling pesssure. Due the 30th so just wondering if these symptoms will last until then or longer??
