name regret

My boyfriend and I decided on Jordyn Olivia when we found out our baby was a little girl. We still have 15 weeks left, but we have already announced to everyone what we are naming her. I can't shake the feeling now that when I see her something different is going to come to mind. So I've been thinking of other names. Is it weird to feel guilty over this? Lol. I just think I could find something better for her
