FTM what to tell work!?

Vic(Tori)a • Just trying to make sense of this mixed up world we live in 🩷

So I just found out I'm pregnant about 4w 4d. And I work in housekeeping/laundry at a hotel, which at times is quite physical. so what I'm wondering is, when would be a good time to tell my boss I'm pregnant? I don't wanna tell too early in case something happens, but I don't wanna be pushed too much if the job is getting too physical. What's your advice?
