i told my boss right away...
That's reassuring to hear they were understanding! I know your employer isn't supposed to shame you or make you feel uncomfortable, and I don't think mine would at all, but it's nerve wracking!!
I told my work when i first found out i had only been there 2 months but they were understanding and got me the papers i needed for my doctor to fill out for fmla and got everything taken care of
I could tell them now I told them when I turned 12 weeks.
It depends on what you do for a job. If you do heavy lifting or are exposed to things you shouldn't be while pregnant, you should tell them now. If not, it's up to you. With my first I told them once I was 20 weeks.
I told my job right away then again i have been there for almost a year i was about 6 weeks when i told my boss
