Work situation 😁

Hey ladies! I found out I was pregnant the day I interviewed for my first job as an RN. Obviously, I didn't say anything then or at my second interview becuase I didn't think it was pertinent to me doing my job. Still don't--but my question is--now that I have been offered and accepted the position, should I tell them now before I announce my pregnancy publicly? Or do you feel like it's not that big of a deal? Thanks y'all!
