Caroline was unsure of how she would know when her water broke, so she asked me what she needed to look for. I told her, When your bag of waters breaks, it isn't usually just one gush of water, with no further leakage. There is often a gush of amniotic fluid, usually followed by a leaking of small amounts of fluid. Women describe it as a constant wetness or water running down their leg when they stand. Continual leakage of water is a good clue your water has broken.
Amniotic fluid is usually clear and watery.
Occasionally it may have a bloody appearance, or it may be yellow or green. It isn't uncommon to have an increase in vaginal discharge or to lose urine in small amounts as your baby puts pressure on your bladder. But there are ways for your doctor to tell if your water has broken. Two tests can be done on the amniotic fluid. One is a nitrazine test.
