Hospital bound 32weeks

So I had an ultrasounds Monday due to my doctor being worried about the baby's growth, I was measuring 29 weeks at 32 weeks so today the ultrasound came back and the baby's lung development was slow and the baby was a bit small, so he admitted me now I gotta take two shots of steroids to pump the growth of her lungs and hopefully not get indices but if I comes down to it I'll be having the baby probably tomorrow. The app says the baby shoul be weighting 3.9ppunds but the doctor said she weights 3.15pounds so what the heck?? The nurses were even wondering why I was here until I told them about her lungs, they said I was small and long so I could just be carrying the baby differently. The girl I share my room with is loud and honestly just very annoying I wish a had better coverage so I wouldn't have to share a room honestly. But anyways any tips on what I should do? Any questions I should ask? This was mainly to vent.
