I'm not pregnant. I don't know if I ever will be again but I already decided not to tell anyone the names. I kept it a secret with my first and it was lovely having that surprise for others. And also I didn't put up with any remarks or insensitive comments. My other two I picked their names while pregnant and referred to them as that. Got comments all the time.
The only other option is pick a name and refer to the baby as said name and then when baby comes along give it the name you picked all along. A decoy lol. Then if someone steals it you get the last laugh.
