Low Amniotic Fluid-27 w 1 Day

I need advice... My amniotic fluid is low and my baby's abdomen stopped growing four weeks ago. She's already in position and trying to come out. I had to call 911 after having contractions all night that wouldn't stop to find out this news.... I have an appointment with my OB Tuesday the 19th. He's going to do an ultrasound and see for himself. What do u think will happen ??? Anyone to threw anything similar????? I'm just scared. I'm only 27 weeks 2 days ....
