Preterm labor question

Brittany
I was admitted Sunday for preterm labor. While in triage I progressed from a 1.5-2. They started magnesium sulfate that night at 7pm (I had a steroid shot at 5). My contractions finally slowed and spaced far apart. I got my second steroid shot yesterday and they turned mag off at 10pm. 
I got moved to am I an observation room and just had an nst. Baby is looking good! 
My question is have anyone been in preterm labor and when did you deliver? Everything is all up in the air for now and it's driving me crazy. They can't tell me when I'll be released and that is killing me 😔
