Gush of discharge! Help!

I was folding laundry and instantly felt some what of a gush. I actually thought since I been having alot of pressure I peed or something. I go to the bathroom to wipe and have a big amount of discharge clearing white and stretchy and slimy like. Earlier I had less of a amount of discharge. Is it normal in one day for this to keep happening. Currently I just turned 34wks
