For what it's worth, I was breastfeeding with long cycles and am vegan, and those things are supposed to sway girl. I also had the exact same pregnancy symptoms (cravings, nausea, etc.) with my second as with my first (who is a girl), and I had a boy. I wasn't trying to sway at all considering we weren't even TTC -- I wasn't even supposed to be fertile and was temping and using a diaphragm -- it's just that the things I was doing happened to sway girl.
