I've been taking vitex 2 weeks on, 2 weeks off to bring back PPAF, timing it to line up with my former cycles (which were 28 days) since I didn't know when to start. I'm on day seven off vitex and my period is starting (yay!). Am I right in thinking that I should count tomorrow morning as cycle day 1 and start popping vitex again for the next 14 days?
