I'm 17 weeks 4 days and have not told anyone I'm pregnant. The father is a jerk who's given me a hard time especially since finding out I'm pregnant. My family gossips and I can't stand my older sister who's evil so I don't want to tell anyone. Not sure how long I can hide this. Not really showing yet. Also having a hard time telling my autistic son that he's going to be a big brother since he understands things different from kids deemed normal. Feeling down and depressed and mad as well as disappointed in myself for being pregnant by someone who has treated me like absolute shit.

Any words of encouragement? Thanks.
