For The Past Few Days I Have Been Leaking Alot

For the past few days i have been leaking alot of fluid from my vagina. It reminds me of when my water was leaking before it broke when i was pregnant with my daughter. Its so bad that when i get up or walk around to much it will gush out and i have to go and change my clothes due to it looking like i have wet myself. What is this and what is going on? BTW i have had my tubes tied for 3 years
