Gender Swaying for a Girl?

Taylor
Is anyone gender swaying? We want to try for a girl since we already have a boy. The research I've done says to keep pH levels as low as possible (using repHresh or a wash to maintain pH level), take Vitex supplements, DTD 2-3 days before ovulation, use the jump and dump method after BD, and take Benadryl or another antihistamine for the 2-3 days before ovulation. Is anyone else using these suggestions or has anyone used it and it work??
