Telling new boss I'm pregnant

Jessica

So I just started a new job and literally the third day of my new job, I found out I'm pregnant. I'm almost 5 weeks pregnant.

How long do you think I should wait until I tell them? Like when I start showing? I don't want to wait too long because I want to give them time to prepare and such. But I don't want them to think that I'm incapable.

Thanks in advance!
