Check out fertilityfriend.com I don't know much about yourdays.com, but it sounds like you aren't monitoring your fertility signs. Fertility friend explains all about them and how to check them, and it has a program that uses those signs to tell you exactly when you ovulate. It's much more accurate than just counting days from your period(I'm not sure if this is what you're doing, but it sounds like it).
