hi, you must do what you think is best, dont be influenced by anyone especially your dad.. i think all dads say that.. when my dad found out i was pregnant he was gutted... said "oh your not are you" he was so disapointed.. i was 34! i think all dads are especially protective to daughters.. whatever age.. you just need to ask yourself are you ready? if you are then embark on what is the most fantastic journey... theres nothing like having a baby to love to nuture.. they depend on you solely and that feeling is the best in world.. i wish i had been younger when i had mine.. but im just glad i did.. i always said i never wanted children, mostly because my dad was really old fashioned.. he didnt beleive in children out of wedlock.. he even always said he would disown me.. so i never had any.. but i reached that point where my desire so children overshadowed my father.. he passed away two years ago, and he told me he was proud of me just before he died, he also told me my son was beautiful.. that was his blessing.. after my son was born.. not before.. your dad will come around .. just give him time..
good luck..
