How to tell if it’s amniotic fluid?

Sarah

So after I went to the bathroom, emptied my bladder, I went to wash my hands. All of a sudden a small gush of clear, no smell order made my underwear soaked. I’ve had no contractions, baby has been moving as usual. Should I be worried? Or is this more joyous discharge. Besides smell/color how do you tell the difference? Thanks ladies, sorry for all the gross info :)
