Failed frozen transfer

Zo`e

Another transfer completed and another one failed. I wish my body would just do what it is suppose. I am starting to feel like a failure and I am Never going to be able to fall pregnant. I have one more frozen embryo. I don't know weather to wait a few month and have some time off to try lose some weight and clean up my diet. I am not over weight but I am also not the healthiest with my diet. Help did anyone find having time off helped or anyone have a third transfer and it was third time lucky?
