Not confident with the name I have picked out

I'm kind of in a bit of a struggle here, I already have my daughters name picked out and have told everyone and have it posted everywhere and even have the letter in her room, it wasn't my first choice for her name but it was the one her father liked the most out of the names I had picked. Idk what to do I just don't want to regret giving her that name that isn't my first choice and I'm already almost 38 weeks
