Wrong gender!!

So 2 weeks ago at my ultrasound the tech told us it was a boy. My fiance and i started shopping for a boy. Well 2 days ago we had a 3d ultrasound done only to be told its a girl!! After spending money on boy stuff...i was so excited thinking it was a boy bc my fiance only has 3 girls. Since finding out its a girl i feel like that bond is gone:(
