please tell me I will feel something ...

I'm 12w5d and I feel no attachment to this baby whatsoever....no emotional or physical attachment. I feel bad and I want to feel something but for some reason I don't....what's wrong with me? Will this change? 
Also I was hoping for another girl and he ultrasound tech guessed boy and now I have to wait till I'm 20 weeks and I guess I'm a little sad it's a boy (I know...so silly) 
I think the reason is, is because my husband wants it to be named after him and I don't....I want him to have his own name. Idk I just don't feel right with this pregnancy. 
With my daughter I was attached to her from day 1. 
Thanks for reading my vent 😊
