My weight is always an issue

In March I went to the doctor for infertility issues. They did blood tests and it came back that I have PCOS. I weighed 279 lbs. The doctor recommended that I lose weight and that it would increase my chances of getting pregnant. I'm down to 230 lbs now and still pushing to lose at least 60 more lbs. I weighed 175 when I got pregnant with my son. So I'm hoping that losing this weight is my answer to conceiving again!
