I did Cohens which isn't marketed as a TTC diet, but Dr Cohen is a fertility Dr and created this diet to help women TTC a baby.

I did it for 14 weeks and got a BFP with this baby. Before the diet my AF was arriving anywhere between 34-71 days. In the 14 weeks I was on Cohens, my AF was great.
A lot of women who start the diet are told to be extra careful as it does make it easier to fall pregnant for most. Someone else who was doing it at the same time as me is also pregnant and due 30 days after me.

Wishing you all the very best for a short & successful TTC journey
