TTC after tubal and an ablation: Is it possible?

Hi my name is Angie. I'm 34 and I have two healthy, half grown children. I am married to a wonderful man who has no children of his own. I would like to have one more :) But in 2002 I had a tubal thinking no more babies for me. In 2011 I had an unexpected ablation for heaving bleeding. Now I've researched pregnancy after a tubal and some have been able to. I've looked up pregnancy after an ablation and it's high risk but possible. But could it be possible after both? We've been actively trying for 4 months. Any thoughts are much appreciated :)
