At 30 week appointment I had a growth ultrasound that showed my amniotic fluid was up to 29. Came back today at almost 32 weeks (in two days) and my numbers went down to 21 already? Does amniotic fluid normally decrease that fast?

My doctor also put me on non-stress tests and ultrasound to check fluids at every appointment until Baby is born. I’m not sure why though if my numbers went down so quick?

Anyone have experience with this?

My stomach is still measuring 2 weeks ahead size wise.
