Help please!

Mon-Wed of last week I had a white mucusy discharge (kind of a lot) then Friday baby hadn't moved hardly at all and my stomach was getting really tight, then Saturday I woke up and my underwear and shorts were wet, all day my stomach got really tight every 15-20 minutes, not sure if it was contractions and baby moved just barely that day too, yesterday my stomach continued to get tight but I tried to ignore it, so I didn't time it, then today so far baby has been moving and stomach has gotten super tight and hard a few times. I'm 35 weeks 1 day, what could this be? Anyone else had anything like it? I gp to the midwife tomorrow.
