FTM cervix check question

Elizabeth
On Thursday I was checked and told by my doctor I was 1cm and cervix was soft, went to L&D on Sunday for contractions that were 7-8 minutes apart (live 45 minutes from the hospital) the nurse check and said it was closed but soft.. And I was sent home after 3hrs... Is that even possible?  Not sure what it means when cervix is soft 😕
