Can I still get pregnant?

Long story short. I used to have anorexia and suffered for 4 years with it. My periods were messed up. They were irregular and there was times when I wouldn't get it for months. I met my bf three years ago and went on the pill so I was getting a period. I was still sick when I was seeing him. I got better and made full recovery two years ago. I've been in the pill for three years and put on lots of weight and am healthy again. I recently went off the pill a month ago as we are trying for a baby. My period is back in on it now. And because I am so much heavier and healthier I would expect it to be normal. I'm worried about infertility. And that I may have messed it up big time. My doctor said I should be fine but has anyone had experience with eating disorders and messed up periods and been able to conceive??
