Polyhydramnios (extra amniotic fluid)

Has anyone been diagnosed with this? I'm 37 weeks today, went in yesterday for an appt and was there for 3 and a half hours. First my Dr said that the heartbeat wasn't as strong as it should be and ordered a stress test to be done where they monitored me for contractions and the baby's heartbeat for 20 minutes. But the little stinker wouldn't stay still and the nurse told me she's head down but facing my belly not my back, so my Dr then ordered a biophysical profile. I guess they test for 8 different things and she passed all 8 but then I was told I have more fluid than I should. I'm not measuring big anymore either. So I'm just wondering if anyone else has gone through this?
