Low amniotic fluid

Thursday night I was admitted to the labor and delivery unit for low amniotic fluid during a routine growth scan. I was put on Iv and the next day they checked my AFI with the slightest improvement. My fluid was boarder line low and normal. 5.6. My ob released me and wants me to see her 2x per week to check baby's fluid. Has anyone been through this and what are the chances of a full term delivery?
