I told my job as soon as I found out. Only reason is because I am having twins so I have more appointments then I would have if I was having one child. So that means missing a lot of work. And they didn't mind.
I told my job like 2 days after i found out, they took it fine, didnt put me on lift restriction until i was much further along. Im 24 weeks now
I didn't say anything until I started showing then people started asking so I ended up just telling them which was towards the end of my second trimester
