When is it okay to tell my boss I'm expecting? I work in a corporate office.

2nd trimester

I told my boss at 4. Id say it depends on the relationship you have with them. My boss, supervisor, business owner and my co workers were so extremely excited for me! They cannot fire you or let you go for being pregnant.

my boss knew before I did lol. really glad she did because I've been on bed rest since 15 weeks

Thanks ladies!
