I just read an interesting article about some common myths about fertility and ttc, such as standing on your head after sex. Most of them I've seen talked about on the boards in some aspect before, although there was one I haven't seen mentioned (aromatherapy).
What do you think about the article, are you trying any of these? I think there is some basis that yoga, and other stress relievers, help even if there is no direct link because your body is healthier if you can relax and de-stress every now and then.
