Yes, if it's well ventalited it's just fine. Also, how strong is the smell? Some wood stane is stronger smelling than others. I'd also say wear a mask when you do it as well. I did some wood working projects when I was pregnant with my first pregnancy and it did not cause any issues.
Thanks I figured that as long as the smell isn't strong that it is bothering me then I'm fine, and of course if I'm not light headed or dizzy. But I know there is brain development at this time and I want to make sure it's safe.
My personal opinion is that if you are working in a well ventilated area you should be fine. I'm 13 wks 4 days pregnant and I have been hanging sheetrock, using joint compound, painting, etc. The area I'm working in is really large so the smell is barely noticeable. I think you will be fine as long are you aren't in confined space and working for hours at a time withotu fresh air. You can also where a face mask if it makes you feel better.
