Checking dilation

A

My doctor checked me today if I'm open and to ky surprise I was not even 0.5cm, although she said my cervix is soft and when she removed her hand there was blood all over her hand. She said this is fine. I feel a bit scared this is the first time that happened to me. Is it normal that blood immediately come like that? How will I know if I should go to the hospital? She said it will stop by the evening.
