When is the right time to tell your mother pregnant when you are 17?

You should tell your mother as soon as possible. She needs to know as soon as possible to give her the the chance to be there for you to support you. She may be able to help you with decisions and help you through this difficult time. It is important that you communicate with her so she can be there for you. Don't wait too long to tell her, as she may be disappointed or angry if she finds out from someone else.
