Cervix question??

May be TMI to some... but my dh hit my cervix really hard during sex and it was really painful. I haven’t had any bleeding or spotting though which is a good sign. I do have a few questions though. I am a FTM at 16 weeks so forgive me if my questions sound ridiculous. I’m just concerned.

1, if bleeding should occur, what should I do? go to ER, speak to OB?

2, could this cause a incompetent cervix thus resulting in miscarriage?

Thank you in advance!
