Regulating "Naturally"

I've been without AF for about 4 months. I've been without it longer (a year) but it's becoming difficult TTC. I've noticed when I eat strictly healthy (water, plenty of fruits and vegetables) it will come back like clockwork for the next 3 cycles. After that, nothing! It's frustrating. I know I ovulate because after my last AF I started to use OPKs. Does anyone have any tips or home remedies to get AF to show her face -- lol i miss her!!!!!
