What is happening to me?

So this is a little weird but I was getting up and a hole heap of liquid gushed out my vagina, soaking my pants, lounge and floor. I've never experienced anything like this. It didn't have a smell, I'm not itching or sore down there. Does anyone have any idea what it could have been? I'm late for af by 14 days my partner n I are not preventing but are not "trying" if that makes sense And I'm only 24 years old.
