Parents want me to abort...

So I'm 20 years old and 16 weeks, 3 days pregnant with my first baby. I have finally told all my family and not a single one of them is supportive. My father is demanding I get an abortion or get out of his house. My mother doesn't want me to have the baby. My boyfriend's family on the other hand are all 100% supportive. My boyfriend and I really want our baby but my family doesn't think we can do it... I need more opinions please. What do you think I should do...?
