My cycle is as regular as clockwork....I have always had O pains on day 14. With DS we DTD on day 13 (once only), got a boy....with our DD (unplanned) we DTD on day 9/10 of cycle (once only), thinking we were safe not to get pregnant...Bingo got a girl. I think that because I was still a few days away from ovulation the male sperm got to their destination and no egg, by the time the female sperm got there (they are fatter, slower and live longer) I had ovulated or was just about to. Good Luck, hope you get the little girl that you desire...
