Am I being petty?

So a few years ago, I was pregnant with an ex. I miscarried the baby (a boy)before we knew what we were going to have but we had names picked out. Emberly Skye, and Zaiden Michael.. Anyways after we split we both moved on and both his new girlfriend and me conceived with our new partners around the same time. Like me she miscarried.. But she stole my baby name and named that baby Emberly skye same spelling and everything.. Which I'm pretty angry about because now I feel jipped like I was really partial to that name and now I feel like I can never use it...
