Telling parents

Cassandra
How do I go about telling my mom I'm pregnant.. I know she'll be mad. And my dad will too. I live with my mom and I'll be 20 in June. I've decided against abortion. I don't have a job and I've kind of led a shitty life so my mom is already disappointed in me for certain decisions (dropping out of HS and beauty school) I'm just scared.. I've been with the dad for 3 years so it's not like I'm whoring around.
