I had my 28 weeks appointment on Wednesday and they thought I was measuring large (but it's hard to tell, since I had a pretty pudgy belly before pregnancy too), so the midwife ordered an ultrasound for this morning. At the ultrasound they decided I've got borderline low fluid (8.2 cm AFI, in the 2nd percentile for gestational age). Baby and placenta looked great - they checked kidneys, cord flow, everything. The midwife later checked my cervix and determined there was no fluid leak.
I'll go back in a week for another check. A "high risk" OB came in to talk to me about low fluid. Mine isn't dangerously low, but it's pretty low and they want to keep monitoring it. I asked if drinking more water could help and he said it wouldn't make any difference (!). Afterwards, the midwife told me to drink tons of water.
So, here I am drinking tons of water. I've also read that maybe I should try to increase my salt? Anyone else have ideas for improving AFI? Has anyone gone through this? Does this make it less likely I can have a nice uncomplicated birth?
