Telling parents

Daniela
Okay so I'm 19, and I'm about six weeks pregnant with my second baby. I don't live with my parents I live with my fiancé but I'm like really terrified about telling my parents that I'm pregnant again. Mainly I guess it's because my mom is like a 'speaks her mind' type of person and she'll say the first thing she thinks. Like with my first baby I didn't get to tell her because someone went and opened their mouth before I got to tell her, I don't know. But I plan on telling her today that I'm pregnant but I don't know how to bring it up
