weight and infertility

This is a really hard struggle for me and I've never shared it. Ever since I was 8 or 9, I've struggled with my weight. I have dieted, struggled with eating disorders, gotten severely depressed over. I have been irregular since I was 13. I have been ttc for a year and a half. Just this past week, my husband and I decided to give it a break. Has anyone here successfully lost weight and successfully got pregnant as a result of doing so? If so, how did you lose it & how soon after were you able to conceive? Thanks so much ladies.
