Just looking for a little advice really, I don't want to unnecessarily panic or take time from the strained NHS if it's just a normal occurrence during the late stages of pregnancy, forgive me it's my first one so I am still trying to figure this new body and it's functions out 
I am 39 weeks pregnant and a few days ago I started getting a bright yellow discharge, it's thin in consistency but does sometimes have a thin jelly like substance. I originally thought it was just general leaking because apparently my pelvic floor exercises haven't been very effective. Anyway.. yesterday there was so much to the point last night in bed when I woke up during the night I thought I had peed, but I hadn't it was this discharge again, all day today it's just leaking out. (I am so sorry this is really grim) Any ideas?
