Is any of this happening?
Be seen today
Any vaginal bleeding after menopause should be assessed promptly.
Most causes are not cancer, but testing is needed to find the cause.
Seek urgent medical advice after hysteroscopy if you develop worsening pelvic pain, fever, foul-smelling discharge, or bleeding that is becoming heavier rather than settling.
Heavy bleeding during a possible or confirmed pregnancy also requires urgent assessment.
