It could also be your plug, I've been having a watery yellow ish discharge for about 3 months now that my doctor says is just a tiny bit of my plug passing along with my discharge. It will grow back, unless it's bloody, but it's also normal I guess. I was worried it was my waters too since it had a slight sweet smell to mine, but she said that was just from the discharge and the yellow (TMI: sometimes a greenish tint.) was just my plug dying small amounts of my discharge as it came out.
