Silly to change the name I picked?

My husband and I picked names out before we even got our BFP he picked the boys name and I picked the girls name. Well my best friends sister is also pregnant with a girl and already announced her name and I now I want to change it. I wanted Harper Marie and she is naming her daughter Quinn Harper. My husband says I should keep it because it's the first name I fell in love with but now I'm not so sure. Insite?
