I had my tubes tied 2 1/2 years ago and then after that i got the novasure ablation done. would i be able to get pregnant if i get my tubes untied?

Unfortunately no: An endometrial ablation destroys the endometrium or the lining of the uterus. The endometrium is required for implantation of the embryo. Sorry, you will not be able to become pregnant.

Chances poor: Probably not. Most responsible doctors would hesitate to perform a tubal reversal on a woman after novasure, it would be arguably irresponsible in many cases. There are reports of women conceiving naturally after ablation, and the complication rate is high. Bets of luck!
