Pregnant

I'm 16 years old and I've been involved with this older guy who is 23. I lost my virginity to him and on that first time I got pregnant. I'm in college and I work, but that still doesn't excuse the fact that I'm so young about to have a baby. I'm nervous overall because I don't know what to do or where to go? I can't believe one bad decision is about to turn my whole life around.
