Thanks for your query.
Read and understood that you are taking antibiotics for PID or STI for 5 days. Ideally symptomatic relief should have been there in the form of no pain or bleeding.
This indicates the need for clinical re-evaluation, physical examination, ultrasonography and other tests to see the probable cause and option for another / additional treatment.
Consult your Gynecologist ASAP.
I hope this answer helps you.
