Trouble picking baby names

This is my first baby and up until 18 weeks I believed it was a girl. I even went as far as to pick out a girl name, which was my mistake. I'm over the moon happy to be having a baby boy but I'm having a really hard time finding any boy names that I feel attached to like I did with the girl name. Did anyone else have this problem? Everyone seems to be giving me grief for not having a name picked out but I'm only 24 weeks and it's alot of pressure to decide on a name that will be a person's identity.
