Freaking out

kaytlyn
I'm 25 years just find out I'm pregnant. My boyfriend and I have been together for four years we are not married or engaged. My dad is VERY old fashioned and I don't know how to tell him. I'm so afraid he will be mad and disappointed.i need advice on how to break the news. This would be his first grandbaby but I'm also his youngest child and unmarried. Please help
