Runnermum - I had started taking the Vitex after hearing so many success stories with it. If you click on my FF chart and have a look at June, August and October I had fabbo charts and +ve HPT's and BT's,but just couldn't seem to hang on to the bubba's. I am not sure if the Vitex had anything to do with it all but I have stopped taking it now because it made me go troppo, and I mean I was out of control. My mood swings were so horrendous I was even yelling at our fish.. LOL... Best of luck..
