The difference between amniotic fluid and secretion is mainly in the speed of effusion, character, and the judgment of PH test paper. 1. Speed of effusion: Amniotic fluid usually shows continuous effusion, especially for those with low rupture of fetal membranes, the speed of amniotic fluid effusion will be faster. The secretion is usually slow and intermittent, and usually has no obvious feeling. 2. Characteristics: Amniotic fluid is clear and watery, but after being contaminated by meconium, it may be yellowish or yellowish-green, with the presence of fetal fat. The normal secretion of women is generally milky white and has a certain viscosity. 3. PH test paper: For those who have amniotic fluid, the amniotic fluid is alkaline and will turn blue when tested with PH test paper. The normal vaginal environment is acidic and will not turn blue when tested with PH paper. During pregnancy, if there is any abnormal water or fluid flow, it is recommended to consult a doctor in time to determine whether the membranes have ruptured, and then follow the doctor’s instructions to deal with the situation.
