As far as I'm aware you should eat a healthy diet without too much caffeine & alcohol while TTC. I know a lot of us act as though we are pregnant after ovulation just in case - ie no soft cheeses, alcohol etc etc. For me personally, I let go while AF is here, also for about a week after & will have a drink if I feel like it. Otherwise I act as though I am pregnant for the rest of the month.

I'm not a mushroom eater, so have no idea about that sorry.
