So today I found out I'm 5 weeks pregnant, I'm honestly very excited! But I'm only 17 I turn 18 in May, and my parents always told me how strongly they don't want me to have a child while I'm this young because they did. I don't know how to tell my parents but I know I need to. Any help? Anything please. Plus I really don't know what I need to do I did tell the dad though.
