CD 75... : ( vitex or fertilaid?

Happy holidays all! Had to come into glow this Christmas morning to press the "period is late" for the thousandth time. Really want to look into anything that can regulate my cycle naturally. I had irregular periods to begin with. Was on BC for years. Removed Nuva ring in August had one period induced by progesterone pills in October and two monts later, nothing. Not even sporting. Anyone know anything about vitex or fertilaid, did it work for you? After you stop taking it will your body revert back to irregular cycles?
