Opposite thing happened for me: I O'ed 3 days late and we bd a couple more times thinking we were in the clear. My oopses got me pregnant, but I don't know if the oops sperm got in or the ones for a 2-day cutoff (which was really a 5-day). I completely understand your worry!!!!!! I do still think that you probably have a better than 50% chance for a girl (but certainly less than the 85% or so with a strong sway). You've been doing the diet and supplements, which are some of the most important sway factors. With the diet, everything was certainly different from when I got pregnant with my boys, so I still have hope.
