I recently landed my dream job as a PhD-level researcher in a tech company. I am scheduled to start the new job this summer. However, I found out after I accepted the job that I am pregnant, due in early December. I am worried that when I tell my new boss he'll find a way to withdraw my job offer before I begin. On the other hand, I don't want to surprise my new colleagues by showing up pregnant on my first day. I am the first woman ever hired onto this team and I don't know what to do. Any advice?
