Help :(

Katherine • Pregnant with first baby with my hubby!!
So I've had low amniotic fluid since 20 weeks, lowest it's been is an 8 it got better because I drank a bunch of water and then it went up to a 13. Now it's down to a 9.... When I went to the doctor today he said that if my
Fluid level doesn't go up to a 10 by tomorrow he's gonna put me in the hospital to receive steroid shots..... For the babies lung development. I'm so frustrated with this, I'm only 24 years old I don't know why I'm having a high risk pregnancy.... He said its the placenta not working properly. I'm just so over this.... Any words, or anything for anybody that's Been through this would help GREATLY. And I'm 23+ 3 days. 
Thanks for listening
