when do you tell your employer youre preggo?

When I was 3 months along

I just started working here and I'm already 17 wks today @reaganmommy2015

I told mine as soon as I found out bc my dr didn't want me lifting more than 25lbs and I was working in a restaurant where I was lifting 50+lbs though I didn't tell my co workers till I was 4 months along

i told my manager as soon as i found out.

I told them when they wanted me to lift a 50lb sack of potatoes. . I was 6.5 months

I was working 8 months in my job and told them when I was 11 weeks

I told mine at 15 weeks
