Hello. My name is Pat and I'm 61

4 months ago I had odd day bleeding.  My gp refererred me to gyno. On examination she found I had thickening of womb and  took a biopsy. Then she fitted me with a  cancer coil. The pain was horrendous. Since then I've had cramping period pains very sharp stabbing pain either deep in middle of legs or lower stomach and have bled every day since but mainly after I have been toilet to urinate or other.  It's then very bright red that eases to pink till I go loo again.  
is this normal.  I'm so tired and depressed
