I haven't used Fertilaid, but I have heard great things about it. Fairhaven Health has a youtube channel w/ reviews of all their products and Fertilaid for men and women get great reviews. They do say that it can take up to 3 months taking it to get a BFP though.
I have an OvaCue, just waiting on AF to start using it. If soy doesn't work this cycle I'll be buying fertilaid.
