Changing your mind about the name choice?

Hi everyone! I'm feeling quite stressed. I was pregnant at the same time as my best friend, which was super nice, and she gave birth this week. My due date is in about a month. The name we had in mind for our daughter is Feline. And you guessed it, my friend's daughter is named Philine. It's spelled differently, but still feels a bit too similar. What do you all think? Should we change the name at the last minute to our second choice? Or just keep it as is? By the way, our second choice is Sofie...
