My parents first named me Lindsey. I have quilts and all kinds of stuff that say Lindsey from my mom's shower...my name is Cody, they changed their mind last minute in the hospital. Do what feels right for you.
Technically, it's never set in stone. You can always change your name in the legal system. It's just a hassle.
Yeah just make sure you decide which you like more. The only thing is once your baby is born and you sign papers for your baby's name it's set in stone then.
It's your baby name her whatever you want.
