wrong diagnosis

I ended up in hospital last week. Doctors suspected my waters had gone examined me but didn't take a swab to see if they had ended up having steroid injections and put on antibiotics and stayed in hospital at the end of the week had another examination and was told my waters didn't break. I'm annoyed because I stayed in hospital and had so much stress and went through loads for nothing. Had a scan and now they are saying baby has too much fluid around him. I'm being told so many different things and don't know what to expect or do as this is my first pregnancy. Anyone else been through this
