Hi Kate - thats weird.... I heard you SHOULD drink green tea while TTC, something to do with the antioxidents or something improving cervical fluid. I'm not an expert though. You hear so many things. I got Kaz Cooks Up the Duff book yesterday (I'm not UTD yet) and it has a whole section on herbs to avoid, essentail oils that cause miscarriage, and vitamins too. She says that Vitamin A is the worst... it can bring on AF apparently. Good luck hun
