How to tell my parents

I'm 17, I just found out yesterday that I'm pregnant, my boyfriend (same age as me) is the best. he was super excited when we found out together, he is the sweetest guy, a hard worker (hes a manager already, gets guaranteed 40hours a week), and I've never been happier with anyone. we weren't planning on it, but he told me he would be happy either way and he wasn't lying, hes so happy it made me excited 😂 and I know i really want to start a family with him. the problem is, my parents don't really like him. just because they think he's using me, I give him rides to work and things because he can't drive yet (work takes up the days the dmv is open), but he pays for my gas to make up for it and now that we know I'm pregnant hes determined to get his license. I got kinda side tracked... oops 😂 the purpose of this post is how to tell my parents. (I'm terrified of getting kicked out)

side note: my mom and I share a birthday, she had me when she turned 19, so she was only 19 by hours. I think I'll turn 18 by the time I have it so does she really have the right to judge??? she's always told me how much of a pain raising a kid at that age was.

another side note: we are leaving for Spain on the 21st for a week. before or after the trip???
