Colitis or collagen

I recently had a collagen injection for incontinence but am having bowell problems and mild cramping.  I also passed a large blob of clear jelly like substance.  Could this be some of the collagen and what harm can happen if it was? The dr. mentioned that he wasn't happy with the nine o'clock injection.  I still have mild cramping and have several movements a day where as I am normally constipated and have one a day if I am lucky.  It is also very soft instead of the normal.  I am on meds still but wasn't when this first happened.
