Watery discharge

Hey ladies! :) I have a slight problem that I have noticed! It's not normal for my body! Well first of all I have irregular periods sometimes and I am 4 or 5 days late, and yes I have unprotected sex. I've never been pregnant before and I don't think I am pregnant...😳 But the past two days I have had some very watery clear discharge, no itching or anything like that. Just watery discharge. I know we all have discharge of some type I usually have some but not so thin that it's pouring out like it has been. Anyone else experienced this? Or does anyone know what may be causing it?
