8 weeks pregnant can I sand and stain wood?

We had our first appointment yesterday at 8 weeks and heard a strong heartbeat!

I work with wood so I use stain, paint and am around a lot of saw dust.

My husband has been doing everything for me until we talked to the doctor but my doctor said I am okay to use everything as normal. I just don’t know how I feel about that. He said I would literally have to drink the stain for it to hurt my baby. Anyone have experience working with stain and standing?
