Fertility issues are upsetting and weight issues are a sensitive topic too.
. Please try not to take it personally regarding your treatment at a clinic and weight. They have some sort of guideline numbers for the procedures to work and you want a healthy pregnancy. It is not an attack against you personally although I can imagine it feels that way. And it can be hard if you are stressed out and upset about fertility issues, using food to help ease your stress.
You can work towards losing weight. Eliminating bread carbs, all junk food and sugar really helps me and actually increases my energy. Don't let this hurdle stop you from working towards having a baby. I hope you feel better.
