I Had An Endometrial Ablation In September Of Last Year.

I had an endometrial ablation in September of last year. My last menstral cycle was this past March. It lasted 2.5 days. I have not had a cycle since then. I took 2 pregnancy tests - 1 week apart from each other and they were both negative. I have been severely bloated/weight gain since april. What is the likelihood of becoming pregnant after having the ablation
