I do not know if there is anything specifically geared towards pregnancy- I am sure there is. I like the 'skin deep' section on the environemental working groups page. Please know it is kind of overly-cautious, but at least you can see why somethings are worse for you than others and what the ingredients are that shoud be avoided. Hope this helps! Congrats on your tww! Stick and grow baby!
Don't wear anything scented when you go for your transfer. No perfume, body lotion, don't even wash beforehand with scented soap, says my RE. If your deodorant is unscented, it should be fine.
