I actually just started working with this company I have about 4 months here and I still haven't told them I'm pregnant ... I'm kinda scared I do not want to be fired :/ how do I tell them?? should I wait longer ???
The sooner you tell them the better so that they can plan to have someone temporarily in your spot while you're on maternity leave.
Depending on the size of your organization and your position, there might be a person in HR that is not your manager you can speak with. Do you know of others that have recently had kids? Check with them to see how the process went. Wait until you are at least 12 -16 weeks along, unless you are having any health concerns that might interfer with your work. Since you recently started, are your job duties documented well? If not, create a process for what you do and continue to update the list. That will be helpful for both your manager and the person(s) helping while you are out.
