Help me mostra my parents that I can Amore a child

Help how do I tell my parents that I am pregnant?
I'm 19 and he's 31 that's the first issue they have they think I'm too young and he's too old
I live in another country then them but I been hiding it for 3 months and I always was told to tell them soon as I can but I didn't and I don't want them to yell at me o something for lying o keeping it a secret.
I'm not married yet so people in my family who are traditional o the church because my parents might tell Friends and families who will say to church about my issue to pray

How can I tell my parents
Why is it so hard to tell
Please how can I get them to not go crazy
