Amniotic fluid leaking?

Amber
I feel like I have bombarded my dr with questions this pregnancy so thought I'd ask here first.  The last several days I have been having a clear vaginal discharge. I am 90% sure it is not urine as it does not smell like it, it smells sweet.  There is no texture, just clear liquid.  If I don't wear a panty liner it will soak through my underwear and I have to change underwear half way through the way. Baby ideas??
