Announcing pregnancy

Johnna
So I've told my mom and by so's parents but I'm extremely afraid to tell my dad. I was 16 when I got pregnant with my first and now I'm 19 with my second. I don't live with my parents and the second child has a different dad then my first child's dad. But me and this guy are getting married and all. Any tips on how to tell my dad. I honestly am lost on this one
