37 weeks and having serious cramps

Biblas

Saw blood stain yesterday went to the hospital my doctor did VE and said the cervix is closed but since then I have been having serious cramps that comes goes. I have been wondering if it was the VE he did that caused the cramp like pain and and whenever I go to pee I clean out blood stain. Anyone experiencing this. I'm a bit anxious cause the cramp is very painful whenever it starts.
