pregnant friend

My friend and I are both about to turn 20 and yesterday she told me that she was pregnant, she doesn't know how she feels because she is nervous to tell people but is going to have the baby, she always wanted kids at a young  and she is in a long term relationship, I'm happy there will be a baby around but I feel like this makes me a bad person because she is just starting her life and now it is going to be a lot more complicated.
