Someone took my name!

My husband decided on a name for our son like a month ago and I love it. We haven't told anyone but like close close friends. And then today I get on Facebook and see this girl who's 32 weeks (I'm 21) and she's naming her son the same name. It really really bums me out. Like I felt like our name is pretty uncommon and noone I know around her already has a kid with that name and now literally while I'm pregnant, someone else pregnant picks that name. How do I get over that? Do you get over that? Like you want your kid to have a cool unique name and it then this happens. Idk what to do now. Advice??
