Gender disappointment.

Has anyone else felt slightly sad when you found out the gender wasn’t what you were hoping for? I love this baby with all my heart regardless I just had so much hope for it being a baby girl. I do wants boys too I just wanted my first baby to be a girl and just can’t get excited about having a boy atm it’s killing me and I feel like a horrible person. Especially after our struggle with infertility I just don’t know how to stop feeling this way. Do I just need more time for it to register? Please no hate
