Old friend

So me and my so have been trying for about 8 months. I get stressed about conceiving and the only peace I find is coming up with names. Or other baby things such as baby registries, secret of course. Savings plans etc. well we picked our girl first and middle, then our boy first and middle. I work at a daycare and a new baby came in that was named our original boy first name. So we changed the name. Of all the names the only one I am 100% set on is the girl middle name. Well my old best friend (just grew apart, life moved us in different ways.) is pregnant due next month. Never announced her name, until today when I got on Facebook to see a bump update. It happens to be my girls middle name and I’m so upset. It’s not her fault, I never told her the name, and she is pregnant first. It was just the ONLY name I was set on and i dont know if I should change it or not.

I’m sorry for the rant just really upset! :/
