baby boy wanted baby girl!

Tiana
So I'm
Not selfish I'm over the moon I'm having a baby! I've just mucked up!!
Basically I was sssooooo convinced I was having a girl had the name picked everything I was 10000000% set on the name! 
To then find out I was having a boy my partner has now chosen the name and I'm not keen! But if I'm honest I HATE all boys names! 
I don't wanna sound ungreatful as I truely am not but i think I've mucked up as I don't feel that massive bond? due to me convincing myself it was a girl! I feel bang out of order ;-(
