Given a shot to stop contractions

Hailie

So I'm 34+2 and went into L&D; because of an increase in watery discharge that was filling a pantyliner pretty. Well I was having contractions every 5 minutes that I didn't even notice. I'm still 1cm dialated and 50% effaced like I was when I was 30 weeks. Well to keep me from having my daughter now, they gave me a shot in my arm to stop my contractions. I'm just wondering if I still have the possibility of going into labor soon? I'm just curious because I want to know if I should have my stuff ready to go, hospital bag is already packed, in case I go into labor soon. I'm a FTM so I'm unsure of what to expect.
