As a Periodontist i would suggest you to visit near by Periodontist ASAP.Medicines alone are not enough
Antibiotics or tablets prescribed by a general physician may temporarily reduce infection, but they do not remove the root cause, which is plaque and calculus (tartar) deposits under the gums.
The primary problem is local, not just systemic
Bleeding gums are mainly due to inflammation caused by bacterial buildup. Unless this is mechanically removed, bleeding will persist.
Next Steps
stop your current medicine and consult a Periodontist
