17 and pregnant, HELP !!!

I'll be turning 18 in December and my boyfriend 20 in November. We were trying to conceive and it worked the 3rd cycle. I found out 2 days ago, and I've already told my mom, cause others say to tell as soon as possible.

She reacted by saying I've got no other choice than abortion. (previous family members have gotten pregnant early and my mom is really against that) I don't want her to know we did it on purpose. She thinks I'm on the pill which I was in April 2016 till December 2017...

I'm personally pro choice... but when It comes to myself I don't think I'd ever be able to take away my own kid's chance of a life. I'm so scared of my mom plus when my dad got told he laughed and said, "go to the doctors first and confirm it. If it's positive then just get an abortion, no big deal." it hurt so much to hear that.

Not enough with that, I live in Europe where my boyfriend lives in the United states. We've always been planning for me to move in with him after my last year of education. (We've been together for 2 years)

I really need some advice !!! I'm so scared and confused of everything right now and I don't know what to do...
