Forced to pick a name?

This entire pregnancy I've been undecided of what I wanted to name our little girl. My husband got to choose our sons name so this time around its my turn. However his family was constantly asking me what I was naming her and each time I'd just give them a name from our list and every time they be like, "you changed it again?" When I had never really fully decided on anything just said we were thinking about it  Though when it came time to the baby shower. His aunt and grandmother were throwing it. His grandma told me that I HAD to pick a name because his aunt needed to know for the babyshower. I thought maybe for the cake, yet they could've still just put baby girl or something on it. However I felt pressured so I just went with the name my husband likes (Delilah) however, I can't stop feeing like it isn't the right name for her. I wanted to wait until I had her and decide when I saw her face. Which my husband was perfectly fine with. I had even told his family this on multiple occasions. I'm really not in love without the name Delilah but I feel like if I change it, they're all going to give me sh*t.
