Anyone else having trouble with their pregnancy being a reality?

Okay. I know this question is kind of crazy, but I am just sort of.. confused? Lol. So I picked out a name for my baby and I really liked it. The name is Julia Eden. I loved that name. But now that I have chosen it and declared it as her name, I don't like it and I can't bring myself to refer to her as that or to call her by that name. I think this is because she doesn't feel "real" to me yet because she's still inside my belly where I can't see her. But is anyone else experiencing this or have experienced this too? Though a blessing, this pregnancy was not planned in any way and I'm having trouble with the reality of it. Don't get me wrong, I'm thrilled. Just having some trouble since it's so surreal. Just wondering if anyone else had felt the same way. Also, any opinions on the name? I'm still iffy about it. Ha
