My father was on vacation with my younger brother. My younger sister (16) already knew so I let her know the day I was going to tell my mom so that she could go out or whatever if she was uncomfortable with being around when I dropped the bomb.
My mom reads before bed every night so when she was doing that, I called my home phone in her bedroom from my cell phone downstairs and told her I was coming up to talk about something. Then I sat down on her bed and just told her I was pregnant.. then we had to talk forever and I cried a bit but my mom didn't yell at me or anything.
The next night she told my dad, I worked until 10pm that day so I had to deal with it when I got home but he wasn't that bad either. No yelling or anything whatsoever!
My parents REALLY pushed me to have an abortion but I stuck to my guns, which was hard because after "letting them down" and getting pregnant while unmarried, living at home, and starting college a couple of weeks later... I really wanted to redeem myself in their eyes! There were a lot of hard conversations and I'm going to school while pregnant, which I'm sure is going to be exhausting and really hard at times but I know I need to get this done for my child so I'm going to finish - which my parents are supporting me with, they've paid for everything so far actually.
And while relieved to just have it out there, my parents annoy me so much sometimes I wish I never told them, LOL.
