Thank you for your question.
I am Dr Saha, I shall try my best to help you.
I would advise you to go to ER or urgent care.
There can be a trauma from sex.
An infection is also a possible cause of bleeding.
Site of bleeding needs to be found out & treated accordingly.
Continued blood loss can lead to anemia, shock.
As you can not see your gp right way, you need to get it treated in hospital.
Please try to take plenty of fluid to have good hydration.
I hope this information helps.
If there’s anything else I can do, please let me know.
If you are satisfied, please rate my answer as good or excellent.
