I've been charting my cycle forever and I'm pretty confident about when I O.

DD wasn't planned, but I was charting when we conceived her (through being a bit *ahem* lax..about the rules!) The month she was conceived we BD'd just at the end of my period on CD 6, which would normally have been safe for us....but that cycle I ovulated unusually early on CD10 and we got DD .

DS was planned and we wanted to time it for a boy. I ovulated on CD17 (which is normal for me) and we BD'd that day only - not before, and not after - and got our boy.

Gender swaying is just that - it "tips" the odds in your favour, but like anything there are no guarantees.
