Can I get pregnant if I've had endometrial ablation?

In short, yes.

While pregnancy’s not likely — and not recommended — after ablation, it can happen, so women who have had an endometrial ablation (a.k.a. uterine ablation) should use birth control until after menopause. While it may be possible to get pregnant after this procedure, pregnancy after endometrial ablation can be complicated, so you shouldn’t get the procedure unless you’re sure you don’t want (more) kids. Sterilization may be a good option if you’ve had an endometrial ablation to make sure you never have to worry about an unplanned pregnancy.
