What should I do and not do?🦷

Hey y’all, I am 3-4 weeks in my pregnancy and I am also finishing up dental school next month!!

What should or what should I not do in the dental field to keep my precious baby most safe?

I know laughing gas and most general anesthetic isn’t good, but what about other things? X-rays, the chemicals used, etc.... I was just wondering if anyone would know. Should I tell them in clinicals I am pregnant or would it hurt my chances of getting a job if so. When I bring my resumes should I tell them anytime soon? I give birth March 24, 2023 so there is time. I just know most places don’t really like hiring pregnant women. Just a general question!! Everyone have a blessed day.
