Baby Name Situation.

So there was this baby name that I fell inlove with for my next kid. we are trying and I could possibly be pregnant, so I was really considering this baby name, it is also unisex so I could have used it any way. But a girl I went to high school with that i have on facebook just chose the same name for her unborn son. What would you guys do? would you still use the name? We were more like acquaintances but we know all of the same people. She's spelling it totally different then I had planned. It's a very unique name that I've never heard many with, so I'd be nervous that if I still used the name that her or anyone else would think that I took it from her. What do you think? I'm weird about baby names, I dont want everyone else to have the same name lol Btw the name is Kainnon. Her spelling Kainen
