NaturalChick, I've had problems with soy. During the summer, I developed an itchy rash on my arms and my period went out of whack. I couldn't think of a cause, so I just figured it was something random that would go away on its own. I didn't really think that it was due to my soy intake, until I came across a photo of the rash that results from a soy allergy. The picture was identical to the rash on my arms. I stopped eating soy products, and everything returned to normal.
Cut to three weeks ago, when I was craving fake meat slices and said, "Hey! Soy, in moderation, shouldn't be a problem." Oh, if only. Every morning after I started eating the slices, I'd wake up to a new zit and strange little lumps (not zits waiting to happen, just lumps - like when a mosquito bites you) on my face. I stopped eating the soy products and, again, everything cleared up.
It sucks that I can't eat soy without running into problems, but it's not the end of the world. There are a lot of other options.
I hope everything works out. Keep us posted on the results of your soy-free week.
