Fertility

How can I boost my fertility? I'm off the pill and we have been TTC for over a month now. I order maca root vitamins a friend recommended but I haven't got them yet. We aren't in a rush or anything but my husband isn't home very much so it's making it harder for us to get pregnant on top of everything else. When we decided on this I didn't think it would take this long I guess because we got pregnant so fast with our son. Any advice or ideas would help. Thanks ladies
