Endo and Food

My husband and I have been TTC baby #1 for a year and a half now. My doctor is 99% sure I have endo (without having a lap done to know for sure). I have a hysteropenyagram scheduled next month before starting medication. However, I was wondering if anyone has seen any changes in TTC once they had changed their eating habits? Im very active but my diet is definitely not where it should be. I've decided to give up sugar, processed foods, and dairy completely. Anyone seen any luck with this when TTC? I'm desperate at this point and just want to be pregnant already.
