Polyhydramnios???

Betsy
I am 33 weeks tomorrow with my beautiful little boy and have discovered I have Polyhydramnios (too much amniotic fluid).  My levels are 30.....moderately high, and concerning.  I am getting weekly ultrasounds and non stress tests, but of course I googled it and it scared the crap out of me (higher risk for stillborn, placental abruption, PROM, cord prolapse, and maternal complications and death).  I already have a history of stillbirth, and the risk for stillbirth increases with this.  My stomach is huge and super high, I am so short of breath and uncomfortable.   I am measuring several weeks ahead due to the fluid, baby is measuring right on in the 60th percentile.  I do not have diabetes, and they said they do not see any defects with him that would cause it on ultrasound. (Heart, kidney, stomach defects) so it's idiopathic.  Anyone have experience with this?
