My doctor taught me a method to get a girl/boy. She said the "female" sperm will swim slower than the "male" sperms. But the "female" sperms life is longer than the "male sperms. That's mean she will stay in your uterus for up to ~3days.
So, if you want a girl, you should xx before or at the very beginning of your 排卵期 and the sperms will stay in your uterus and wait for the "egg" to become fertile.
If you want a boy you should xx at the middle of your 排卵期.
I am going to try
