Fertility diet

Has anyone done a fertility diet and it was successful for them? I've been trying for 13 months with no luck. I want to try a couple more things before I look into everything else. I have ordered omega 3 to start taking daily. I've also been reading that if you have a dairy intolerance, which I do, that if you eat dairy it could be playing a role in your infertility. I'm planning on doing a dairy free, low carb diet. Anyone else?

I have tried ovulation strips, temping, pre seed, you name it. I'm just ready to have a baby of my own. I'm also going to start light exercising roughly 15-30 minutes a day.

Anything I should know about a fertility diet?

My periods are semi regular at 28-32 day cycles.
