Parents will hate me

So I recently found out I was pregnant and me and my boyfriend talked about our options but I want to keep it he said he would like to too but he know his parents would hate us and it'd ruin everything. I didn't believe that because they were young parents too. We're 17 and I'm closer to his parents than my own but yesterday we were at his family party when randomly pregnancy was mentioned and his mom said she'd take me to have an abortion that she wants us to graduate first, which isn't for another year, and that we'd be cut off. The subject came up with his dad and his dad said oh hell no he'd beat my boyfriends ass (but jokingly because both these conversations weren't arguments or anything it was random conversations) and when I laughed he said why am I laughing I'm going to Monterey park , to have an abortion. After those comments were said I was starting to feel down and my boyfriend said that he told me that's how his parents would be but we'd get through it. But I'm still worried about what to do , any advice on how to handle this?
