advice for discharge please! amniotic fluid?

Hi ladies, I am wondering at what point should I be concerned about discharge? I have been having gushes for a few months (small but I can feel the liquid coming)..didn't think much of it, my amniotic fluid level has always been normal as seen by ultrasounds. But when I put in a gush of fluid on my Glow pregnancy daily symptoms it said a gush of fluids should be told to my doctor? It isn't a lot or anything, but it is quite liquid (and clear sometimes, sometimes white). Anyone have any advice? (I am a FTM 23 weeks and have been on bed rest for most of my pregnancy, I hesitate to go in to the hospital for this as it is a bit far and I shouldn't drive in a car unless necessary) Is it fine as long as it is not so much? What is a leakage of amniotic fluid like? A week ago I had an ultrasound and seems all was well and my papers says amniotic fluid in normal quantity. Any advice pls? Thanks a lot!
