Going to my dad's to eat tonight. He lives with his mom and my uncle and cousin will be there. The situation is weird and other than my dad they aren't really my family because my dad didn't talk to them for years. But anyways he didn't tell them until I was about 25 weeks that I was pregnant. I'm not sure if they know I am over 36 weeks now. I don't even think he knows because he barely talks to me. I'm stressed out and nervous. please wish me luck!
