My secrest santa was not-so-secret, she revealed herself when she sent her present (which was very awesome).
Talking about the baby dust, part of my gift was some parsley seeds (based on the old wives' tale that you should give parsley plants to ladies TTC), and a week or so later I got my BFP... I totally contribute it to the parsley
I don't think the person I had will even know who I am - I didn't know her till I got her and looked her up - so I don't really mind if she doesn't know who I am (although would happily come forward if she wanted to know).
