Is any of this happening?
Be seen today
Contact a healthcare service promptly for persistent bleeding, blood in urine or bowel movements, repeated vomiting of blood, a rapidly enlarging bruise, or increasing tiredness or breathlessness that may indicate anaemia.
Possible internal or brain bleeding needs urgent assessment even when there is little visible blood.
