I got my princess after 2 boys and this is what I did.
DTD 3 full days prior to Ov, no org.asm, ate lots of yogurt plus a calcium and magnesium tablet. I was also taking a couple of Vit C tabs a day as I had a cold. Don't know if my increased temp had anything to do with it, but so badly wanted pink I would have done the vit c anyway.
Good luck! I read through all the in-gender stuff on conceiving a girl - and decided it was too hard! Picked a few bits I could do easily and went with that. Got my pink!
