When will you/did you announce your pregnancy at work?

I'm 13 weeks and I don't know when to tell them. I only work part time and don't plan on returning to this job after we have the baby.

I told them around 9 weeks. I would be late in the morning sometimes when I wasn't feeling to good. I also wanted to explain why I was sluggish at times.

I think I told my principal when I was about 3-3 1/2 months pregnant.

I was 9 weeks- people started asking

I told them last week (I was 11 weeks), but my bosses already suspected.

I told them at 8 weeks, because I know that they will need someone to fill in for me when I take a year off!

I am 10 1/2 weeks, and haven't told them yet.
I'm waiting until after my next dr.'s appointment - I'll be 12 1/2 weeks by then.

I told my manager the day the my RE confirmed my BFP. She knew I had gone for IUI and I was just so happy that after a year I was pregnant I could not keep it a secret.

i announced at 12 weeks, I still havent told them Im not coming back ( im 34 weeks) I still want to get my mater benefits so i wont be letting them know until after my leave.

I told my principal at 13 weeks and was forced to tell everyone else later on that week because some students started "suspecting" and questioned me on it

I told work at 14 weeks.

When the time comes I will tell them right away as soon as the doctor confirms it, b/c I am not working during the pregnancy. There are too many hazards ( chemicals) where I work.

I will after my first trimester. I am so scared, out of a staff of 12 therapists, there are already three out next year not counting me! My boss is going to lose it!
