I'm starting to get convinced I'm allergic to something at my work as well.
I work at a pet store, and if I am actually allergic to something, I hope it's a bedding or something because I don't care if it's the animals!
I usually spend my mornings (when I take care of all the animals, changing food/water, cleaning cages, etc.) sneezing and with an unhappy nose. Just not sure if it's the dust (from Carefresh, or from the birds), or allergies. I hope gloves help for your issue! That's really strange if it's pregnancy-related...Pregnancy does weird things to your body.
