aftermath of pelvic radiation

I

2013-03-29 I have just been diagnosed wih breast cancer recurrence.  Now it is in my bones.  I have just completed another round of radiation.  This time it was to the pelvic region.  I now have some lower abdominal issues.  I have a slight amount of mucus with each bowel movement and a drop or two of blood.  I have rectal urgency to defecate.  At times I feel nauseated.  Is this normal?
