Im 16 and im pregnant with a little girl. I was afraid to tell everyone but once you do just give everyone time and they will come around. The good thing is is that you have your own place and you and your partner are committed to each other already. I wouldn't stress about it it wasnt as bad as i thought it would be.
Its sounds like your doing great. And dont be scared to tell him.. even if he doesnt jump on board immediatly he will come around. Dads will always see you as their baby girl and when you found your love and now your havinf a baby. Hes just got to let go of his baby girl and let his daughter become the woman she is. Just give him time if he doesnt sound to happy about it he will come around.
I'm 19 and I'm 32 weeks pregnant. I was scared to tell my parents and my husbands parents too. In the end we first told his and they gave us so much crap for it :/ I didn't tell my parents until I moved back to the state where they lived and already married my husband. They were more upset that it took me long to tell them but where happy with the news. I think it shouldn't matter what your father thinks as long as you have your own home and are committed to each other. I thought my dad would be mad but instead he felt really happy and gave me a talk about how I should have told him when I first found out lol. Don't take too long to tell him. Good luck and I hope it goes well :)
