Hi,
How are you? Bleeding during or after sexual contact or post-coital bleeding may be attributed to  infection, possible precancer or cancer of the cervix or uterus, and even trauma or injury.  It is best that you have this checked by your gynecologist for proper evaluation.  Treatment will also depend on the underlying cause. Pelvic examination, blood tests and imaging studies will help with the diagnosis. Take care and do keep us posted.
