I had a spirirtual healing to have a child and now I am waiting to become pregnant. Am I wasting my time?

Eight years ago, I had a tubal ligation thinking that I was truly done with having children until I divorced my husband in 2004 and now am with a wonderful guy of 6 years. I had encountered this man that does spiritual healings and had given a girl I know personally a blood transfusion and she is perfectly healthy. So I took a chance and this man did a spiritual operation for me to have a child with my current partner. Should I really believe or am I just wasting my time?
