PLEASE HELP

I need to ease my nerves. Im 38weeks +2days. I have felt crampy and just yuck since 3:40 am and my husband and I decided to go on a walk tonight. Halfway through my "period" cramps got way worse and I almost couldnt finish our walk. Ive been having on and off sharp pains since yesterday and as of yesterday evening ive had an increase in fluid output... Like almost need a panty liner... I know, gross, I'm sorry. But it has no smell and its clear but dries white and I think I lost the rest of my plug around 8:30am. Should I call labor and delivery or can all this wait it out till my doctors appointment at 9:45am tomorrow?
