Thanks for using Healthcaremagic,
After going through your history, you did have unprotected rough sex, and started bleeding and also took plan B
and bleeding for almost 1 week.
You should consult Gynecologist immediately as hormone tablet can cause irregular bleeding but she will examine you for any tear inside or any other cause like infection or bleeding disorders are to be ruled out.
It can be bleeding from hormone withdrawal also.
Please take care in future to have safe sex
as it protects from unwanted pregnancy
and also protects from sexually transmitted diseases.
Hope this helps you
