You ALWAYS have a chance at a boy!! Timing doesn't sway at all and I got 3 of my 4 boys with at LEAST a 2-3 day cutoff if not even longer.
You cannot tell what side you ovulated from on the basis of O pain. You develop eggs in both ovaries every month and only the best one or two will be ovulated. This means that you will sometimes actually feel worse in the ovary that DIDN'T ovulate because it's swollen with eggs and nothing can relieve the pressure.
Huge congrats and blue dust headed your way.
