Teen Mom Program?

So my mom made me an appointment at a Teen Mom extension program. It allows me to graduate early with full credits so I don't have to worry about finishing school or anything when the baby comes. Personally I don't want to do this extension program; I want to just continue with normal school, with my friends. I want to graduate with the people I have been with my whole high school life. My mom seems very set on sending me to this program, she has left the choice up to me, but it talking it all up and I have a test day next week. I don't know why she is so set on me going; I don't see why she wants me to go so badly. When the baby does come I’ll take probably 2 months off school then would go back and complete my senior year. I want to be there for senior year; I don't want to accelerate past all that and never get to experience it. I'm going to miss out on so much already when the baby comes, I don't want to miss out on this as well. I also don't want a lot of change, I have enough that’s going to change I want to keep one thing normal in my life, school seems to be that constant. Well I’m 15 weeks tomorrow, I can't believe it really. Going really fast, I’m showing now and it's hard to hide it. I'll do an update post soon.
