What Methods Do Doctors Use to Check If Your Water Has Broken?

When you go to the doctor and they think your water may have broken, they first look inside using a special tool called a speculum. This helps them see if there is any clear, watery fluid in your vagina. Next, they might use a nitrazine test. They take a little bit of the fluid and put it on a paper strip. If the strip changes color, it shows that the fluid is more alkaline like amniotic fluid. Another test they can use is the fern test. Here, a drop of the fluid is spread out on a slide and allowed to dry. When it is viewed under a microscope, it may form a pattern that looks like fern leaves, which is a sign that it is amniotic fluid. Sometimes, doctors also use immunologic tests that detect specific proteins found in amniotic fluid. In some cases, they use a simple ultrasound scan near the perineal area to help check the amount of fluid around your baby. Using these methods helps the doctor decide if your water has broken and what to do next.
