Telling my parents I'm pregnant at 15 almost 16

Layya
I wrote a 4 page letter to my parents explaining to them that I'm pregnant , I have very strict parents , and I'm probably going to get kicked out , My dad isn't my real dad , he's my step dad , so I talked to my real dad about it and he's not mad at all , he's being very supportive and wants to help but the thing is he lives all the way in Texas and I live in Maryland , but most of his family lives here but I've never met them in my life so he said that they will help out in any way but it's kind of scary because I don't know them , but he says they really miss me and want to see me ! He says they have pictures of me all over the place . But back to my parents , THEY WILL KILL ME , probably kick me out but I'm trying to be strong ..
