Gush of milky fluids when i woke

This morning.. About 20 mins ago got up to get my 8 year old son up for school and as i stood up and began to walk i had a gush of milky fluid come out. I always wear pantie liners so it caught it. But i put my hand down there and noticed it looked milky but watery. I don't believe its my amniotic fluids just wondering what could this be? Anyone ever had this happened to them? Should i go to the doctors or call in? No cramping and I've been having Braxton hick contractions
