Are Spotting And Smelly Discharge Normal After Ablation?

i had an ablation jan 2010..i recently start having what resembles a period. i have no real flow just light pink noticed when i wipe. along with that there is a foul smelling discharge that is only present during this time. I also have some itching by the end of the day. this lasts for 3-4 days then its back to normal, no discomfort or odor. my question is is this normal after an ablation?
