Low amniotic fluid 32 weeks

Hi everyone ! I’m currently 32w2d, I’ve had low fluid since I was about 20 weeks, but today I went in for my NST & the nurse that did my ultrasound said she only found 1 pocket of fluid measuring 1.6cm, she went to call the Dr to take a 2nd look & the Dr said she saw no fluid at all. She then went to talk to another high risk Dr & after about 20 min she came back & said it was fine for me to come home, to drink lots of water & monitor the babies kicks. I’ve been drinking water like crazy since they told me her fluids were low. But now that they’re telling me that she has little to no fluid it’s scarring the crap out of me. I don’t know what to do. Should I push for them to keep me in the hospital or what should I do ? I just want to get the baby here safely. Should I talk to my OB about my concerns ? If anyone has gone through something similar pls share your experience. Thank you !
