Various factors can contribute to low amniotic fluid in pregnancy, including: Your water breaking. The placenta peeling away from the inner wall of the uterus — either partially or completely — before delivery (placental abruption) Certain health conditions in the mother, such as chronic high blood pressure.

If your water breaks before the 37th week of pregnancy, it's known as preterm prelabor rupture of membranes (preterm PROM). Risk factors for water breaking too early include: A history of preterm prelabor rupture of membranes in a prior pregnancy. Inflammation of the fetal membranes (intra-amniotic infection)

An estimated one-third of amniotic fluid is replaced every hour. This means your baby won't be “dry” even if you're leaking amniotic fluid. But it's possible that ruptured membranes could mean your delivery is imminent and/or that bacteria could be introduced into your uterus.

While it's possible to break the water balloon, causing a strong gush of fluid (known as your water breaking), it's also possible that a small hole could develop in the sac. This can result in a slow leak of amniotic fluid.

Low levels of amniotic fluid are experienced by 8 percent of pregnant woman, (4 percent labeled as having oligohydramnios) and can be caused by a number of different factors, including: Maternal Health Conditions, including dehydration, diabetes, preeclampsia, hypoxia, and more.

The amniotic fluid levels then remains constant until the baby is full term (37 to 42 weeks) when the levels start to decline. Small changes in the level occur as the baby swallows the fluid.

Low amniotic fluid means that there is too little fluid around your baby in the uterus during pregnancy. The medical term for this problem is oligohydramnios. Amniotic fluid protects your baby from being bumped or hurt as you move your body. And it keeps your baby at a healthy temperature.

The water should be clear, but may have bits of 'show' in it. This may be small clumps of jelly like substance and may have streaks of blood. Normal amniotic fluid does not have a very strong smell. You should change your sanitary pad at least every 4 hours.

If there are very low levels of amniotic fluid for your baby to float around in, there is a slight risk of intrauterine growth restriction and umbilical cord constriction during birth. You may also be more likely to have a C-section.

Signs of leaking amniotic fluid Leaking amniotic fluid might feel like a gush of warm fluid or a slow trickle from the vagina. It will usually be clear and odorless but may sometimes contain traces of blood or mucus.

Polyhydramnios occurs in about 1 to 2 percent of pregnancies. Most cases of polyhydramnios are mild and result from a gradual buildup of amniotic fluid during the second half of pregnancy. Severe polyhydramnios may cause shortness of breath, preterm labor, or other signs and symptoms.

Common causes of polyhydramnios include gestational diabetes, fetal anomalies with disturbed fetal swallowing of amniotic fluid, fetal infections and other, rarer causes. The diagnosis is obtained by ultrasound.
