Female problem....gush?

I just got out of the shower, and I dried off. Went to put some clothes on, and it felt like i had water in my hoo-hoo and then I looked down, and a milky white watery substance kind of gushed out, an ran down my leg!! Anyone know what that is??? It kind of smelled weird too..it wasnt gel or mucus like just milky looking water.. help! im 20, and never had any kids.
