hi Bianca Thaver
Less fluid in medical terms is known as oilgohydramnios. This could be due to less secretion by your system or could indicate a problem in the fetus such as urinary tract malformations, obstructions, polycystic kidneys. Usually the abnormalities can be detected on a scan. Its can be treated by amnio infusion. Hope that answers the question
Take care

hello bianca
your condition is called oligohydramnios when the amniotic fluid in the utrerus is said to be less for the period of gestation. it can be calculated using amniotic fluid index and if it is less than 5 centimeters it is said to be oligohydramnios
it is not constant throught pregnancy. it is variable and said to be less if the volume is less than expected
amniotic fluid is said to be less due to various conditions like defects of kidney or urinary tract in the foetus, if the placenta has anomaly in the vessels providing nutrition,
if the mother is suffering from diseases like hypertention or if the membranes have ruptured leading to the leaking of amniotic fluid,
amniotic fluid is required for the well development of legs and other organs.
also for good movement inside the womb.
it is treatable by 1st diagnosing the cause and treatment of the same.
also it can be corrected by amnio infusion.
i would advise you to have regular antenatal check up with regular ultrasounds,
i hope i have answered your question
wishing you and your baby good health.
take care
