change your diet now. not trying to scare you but your diet is crucial right now. and rest.
up your water intake to a gallon a day. cut out ALL, i mean, ALL sugar. eat pure protein and green leafy veges and some orange veggies. salt your food to taste.
no sugar. no refined breads, nada. check labels too.
i believe, and I am no doctor however, you CAN reduce your amniotic levels.
find a midwife who knows her stuff and ask her about reducing fluid levels.
hand in there and congrats on your pregnancy.
