I wasn't at all indicating that you should have durbsed, gorgeous!

It's not something you'd assume would be a common subject on HoP

And, it's perfectly natural for you to want to air your concern/excitement with the community that loves you.
Finn did loads of research into the toxicity of fumes at that time, but like she said in the post I linked to - Pele performed with fire during her pregnancy with no ill effect... so, it's up to you. I'm sure if you ask your obgyn they'd tell you to keep away from all fumes, but that's probably because they don't have a huge amount of knowledge on the subject and therefore provide the safest medicolegal response.
