Low Amniotic Fluid @ 19 weeks

dizzykates

My A/S showed that my amniotic fluid was on the very low end of normal at 19 weeks.  My doctor considers 8-22 (or was it 25??) normal and I was at 8.4.  She requested I have another ultrasound in 4 weeks and emphasized that I shouldn't worry because it is technically normal, but she wants to see it increase in that time.

 Has anyone had this experience and had things turn out ok?  We've already had one loss and I am trying really hard to not to panic.
