This morning I went to jump in the shower and when I took my underwear off, I had runny white discharge going down both of my legs and dripping on the floor.

Is it possible amniotic fluid could mix with vaginal discharge? Or is it possible to just have a heavy amount of discharge at times..I'm 37+4 and have been having cramping and back pain.

I tried googling it, but only found articles explaining that the amniotic fluid is only ever colorless unless something is wrong, then it may be green/brown.
