What do i do?

We’ve had the hardest time picking out a name for our son and we finally have one

The name we picked just so happened to be the one name that i briefly brought up months before conceiving this baby

So once we said we picked a name my sister went around telling everyone that that was the name but we didnt say that was it and no matter how much we say its not shes still telling everyone it is

Ive also made it very clear that we weren’t going to announce it until birth anyway but she doesnt care

Now i feel like i want to choose a different name just because of that but this is the only one we agree on

Maybe im overreacting like my entire family says but idc

Also, my other sister went around and told everyone that i was pregnant before i could announce and my mom posted the u/s before i posted anything about the baby and my husbands family hates me and the idea of this baby so we’ve only heard comments about miscarriage and abortion not being the worst so maybe im already a bit overly sensitive about the whole situation
