Anyone else?

Am I the only one who just can't imagine themselves having a baby? I'm going to be entering my third trimester in just a few days, feel my baby moving, have a bump, and have already purchased clothing and a few essentials, but I feel like this all isn't real. I'm only 19 but I'm so excited to become a mommy so it's not like I don't want this. I just can't imagine having a little baby in a few months!
