Understanding Low Amniotic Fluid at 35 Weeks: Causes & What to Expect

Question
My fluid level was 6.4 at today's assessment and monitoring.  During the NST, the baby's heart rate fluctuated momentarily but bounced back and remained constant.  The RN said it could be due to low fluid level or momentary cord compression, as the baby made a large movement right about the same time the deceleration occured.  I am drinking a 16.9 oz bottle of water hourly and using the restroom once an hour.  Do I have cause for concern?  I am scheduled for a c-section on January 18.

Answer
6.4 is very normal for fluid.  Anything above 5 is considered to be normal.  As you approach your due date, even numbers below 5 are not immediate cause for concern.  It is normal for fluid to decrease as the baby grows bigger and prepares for birth.  Also, as there is more baby and less space for fluid, measurements of amniotic fluid are highly subjective, with two different doctor sometimes getting wildly different measurements on the same women, same day.  If your urine is relatively clear and colorless, you are well-hydrated.  If your baby continues to move and kick as usual, he/she is most likely just fine.
