Amniotic fluid is a clear or very pale straw colored liquid. The amniotic fluid will be odorless or even have a slight sweet smell.
If your amniotic fluid is green or brown colored it means your baby had a bowel movement in-utero and you need to go to the hospital. If your amniotic fluid has blood or a foul odor then you need to go to the hospital as well.
If you are unsure if your water broke or it you peed yourself just smell it. Urine has a distinct odor and amniotic fluid smells nothing like urine.
