Pregant metalsmith - do's and don'ts

Hi, I don’t know where exactly this message is going to but I’m a
metalsmith that mostly works with silver and some gold. I just found
out that I’m six weeks pregant and need to find out the do’s and
don’ts of being a pregant jeweler because I really want to work as
long as I can. We don’t do an casting anymore and if we did, I know
for sure I don’t want to be around that stuff. I’m aware of the
investment but still not sure of doing simple soldering, the pickle,
flux. I know I should wear a ventilated mask but I still want to know
exactly what to do and how to protect myself. IF some one could get
back to me that would be great!

Sincerely, Kara.
