If this was the first time you have ever had sex in your life, it's perfectly normal! You should bleed a couple days this time and for about the next two times or so following.
If you have had sex before, then you may want to consult a gynecologist.
Hi,
How are you? What other symptoms are present?Bleeding after sexual contact may be caused by a variety of issues such as infection, cervical dysplasia, cervical polyps, or fibroids. If it persists, it is best that you have this checked by your doctor for proper evaluation. Pelvic exam and additional diagnostic tests may need to be done. Take care and do keep us posted.
