29 weeks opening cervix?

mr

Okay so I had some cramping when I went to bed and woke up with pink discharge so I phoned the hospital and they just said keep an eye on it so I carried on with my day and the cramping came back pretty bad and so did the discharge. I rang back and went into hospital they took me into labour ward and done an exam and said I was dilating and my cervix has started to open! I got injected with steroids and had magnesium put into my system for her brain and rushed off to another hospital that deals with premature babies. Only to get there and put in a delivery room to be checked again and my cervix wasn’t even open! They said the First Lady was mistaken? I’m still being kept in and the cramping is continuing and I’m due another steroid shot but I’m confused and don’t know what to expect next?
