TTC for a girl

Stephanie ā€¢ Mother to a sweet baby girl born 14 October 2015 šŸ’—šŸ‘‘šŸ’—
SO & I really don't care either way, but would both love to have a little girl. Is there any truth to BD in beginning of fertile window for a girl? If so, how many days before ovulation should you BD & when should you stop? I want to BD enough to get a BFP but also want to increase our likelihood of having a little girl. Any other tips? TIA
