concieving a girl?

missy • Mom of 3 beautiful boys! * :) ❤

I've read that to conceive a girl having sex 2-3 days before ovulation will increase your chances of having a girl. male sperm swim fast but girl sperm live longer. by the time you actually ovulate the male sperm will have died off giving the chance foe the girl sperm to move in. any truth to This? we have 3 boys and are desperate for our little princess! any tips are welcome!!!
