I had an endometrial ablation done 2+ years ago & since then have been great! all of the sudden i now have severe cramps & bleeding. is this normal?

Can be: I see that you are 29 years old. The younger a woman is when she has the ablation, the more likely that she may need additional treatment. I would definitely see your ob/gyn and get tested to make sure that this bleeding is pre-cancerous with a uterine biopsy. And then also you can talk about treatment options from here. Best of luck.
