blood is not normal.
It could be due to ulcer disease or due to varices
secondary to liver disease.
Since the ultrasound
scan shows enlarged spleen, bleeding due to varices is more likely.
An upper GI endoscopy
should be done to confirm the source of bleeding.
If it is variceal bleeding, it can be controlled endoscopically. You may have to be on long term medications.
If it is due to ulcer disease, then you have to be tested for H.pylori infection and treat it if found to be positive.
I hope that answers your question.
