I Have Had Some Bloody Mucus With And Without Stools

I have had some bloody mucus with and without stools for a few days. This started after I had a fairly greasy meal, that gave me a strong burning and sharp abdominal pain with cramping that woke me from sleep. I have been on an aspirin regimen for 5 months that has been causing more frequent burning stomach pain that wakes me at night. I stopped the aspirin and my pain has subsided but still having bloody mucus, not mixed in stool..
