Low fluid

Sydney

So I went to get a 3D ultrasound today bc something in my gut told me to get one even tho they said the baby probably wouldn’t be in a spot they could see her. They looked and found out i had low fluid (I think they said it measured at a 2?) so they have me in the hospital and gave me a steroid shot and want me to drink fluids then look at her again. I’m not leaking or anything. Has this ever happened to anyone else before??? I’m not sure if they’ll actually induce me or not and I’m nervous that I have to wait so long to find out.
