Gender sway??

I would love to have a girl next, and I’ve read up on the Shettles Method. However, you have to stop having a sex a few days before ovulation which lowers chances of pregnancy. Is it worth trying or is it just bs? Anyone know if they conceived a girl right at ovulation?

PS It’s not that I wouldn’t be happy having another boy, it’s just that my husband only wants two, and I’ve always dreamed of having a daughter. In no way would I not be excited about a baby boy!
