I was taking Vitex (for increased fertility Chat Icon) but not regularly prior to my last BFP, which ended in a miscarriage. I then had AF promptly on CD26 and started taking the Vitex every day since then. I ususally O around CD9 or 10 and it's now it's CD 13 and no sign of anything. Does anyone have experience using Vitex and could it delay ovulation like this?
