Well, I'm sorry that talk didn't go as well as you might have hoped. But at least now they know. It takes a lot of courage to be open, especially if you're worried about being kicked out. You did well.
I'm glad you have a place to stay. I'm sure your dad will calm down eventually. Just give it time. And as others have said, do whatever feels best for you. Good luck with the baby! Keep us updated, okay?
