∙ 2012-08-21 01:49:33The amniotic fluid volume is estimated by measuring pockets of amniotic seen in ultrasound. It is then expressed as the amniotic fluid index (AFI). A normal AFI at full-term would be from 5-25 centimeters. To put it into liquid volume measure, there is typically around 800 - 1000 mL during the latter parts of pregnancy.
A normal full term pregnancy is approximately 9 months for a human.
Infertility
It is very rare, but women can menstruate during pregnancy. It is right at the onset of a pregnancy and usually coincides with the woman being very close to her normal cycle.
A normal, full-term pregnancy for a human is usually 40 weeks. However, anything between 39 weeks 0 days and 40 weeks 6 days is considered full-term.

The fetus is held in the amniotic sac, which is full of amniotic fluid. The sac is in the womb.
Yes-you can still have a normal full term pregnancy.
They are full of amniotic fluid and, until birth, have not been inflated.
That is normal. The fluid expands when heated.That is normal. The fluid expands when heated.
No, unborn pups cannot vocalize because their lungs are full of amniotic fluid.
Yes, this is normal. A lot of women have a full period for their entire pregnancy.
DefinitionAmniotic fluid is a clear, slightly yellowish liquid that surrounds the unborn baby (fetus) during pregnancy. It is contained in the amniotic sac.InformationWhile in the womb, the baby floats in the amniotic fluid. The amount of amniotic fluid is greatest at about 34 weeks (gestation ) into the pregnancy, when it averages 800 mL. Approximately 600 mL of amniotic fluid surrounds the baby at full term (40 weeks gestation).The amniotic fluid constantly moves (circulates) as the baby swallows and "inhales" the fluid, and then releases, or "exhales," the fluid through urine.The amniotic fluid helps:The developing baby to move in the womb, which allows for proper bone growthThe lungs to develop properlyKeep a relatively constant temperature around the baby, protecting from heat lossProtect the baby from outside injury by cushioning sudden blows or movementsAn excessive amount of amniotic fluid is called polyhydramnios. This condition can occur with multiple pregnancy (twins or triplets), congenital anomalies (problems that exist when the baby is born), or gestational diabetes.An abnormally small amount of amniotic fluid is known as oligohydramnios. This condition may occur with late pregnancies, ruptured membranes, placental dysfunction, or fetal abnormalities.Abnormal amounts of amniotic fluid may cause the health care provider to watch the pregnancy more carefully. Removal of a sample of the fluid, through amniocentesis, can provide information about the sex, health, and development of the fetus.ReferencesRoss MG, Ervin MG, Novak D. Fetal physiology.

Yes, its normal not to have contractions yet. 37 weeks is considered "full term" but a full term pregnancy is 37-42 weeks.
The amniotic sac is full of amniotic fluid and suspends the baby in the uterus. It also provides a kind of bumper or shock absorber to protect the baby from impact.
A person can live a completely normal life with only one kidney, and I assume that would mean a full-term pregnancy, too.
A normal full term pregnancy is approximately 9 months for a human.
