What tests do you do to know your water broke?

Amniotic fluid breaks, and a small or large amount of fluid flows out of the vagina. It can be tested with a specific chemical test paper. If the test paper is dark green, it can be confirmed that the amniotic fluid breaks. After seeing a doctor, the doctor uses a dilator to check, and the amniotic fluid flows out from the cervical opening. Laboratory tests to find amniotic fluid crystals can confirm this.
