18 & pregnant♡

Okay so I'm 18 and I'm pregnant. I'm considered an adult. I'm living with my husband. Not really married but as a Hispanic tradition when the man asks permission from both parents to move her in, it is for some reason considered as being married. Anyway even though I already am an adult for some reason I still have that kind of scared feeling to tell my parents I'm pregnant. How should I tell them? And when? I'm planning on telling my mom first. Then my dad. What do you ladies think?
