Gender disappointment

Someone please tell me it don’t last :( this is such a shitty feeling. I have a little boy now and I love him so much he’s everything you could possible ask for in a little boy and I guess I just wanted that agian.. however I’m pregnant with a little girl and I know I should feel so blessed because that’s what most couples want, one of each but I can’t shake this feeling. I know I’ll love my daughter just as much as I do my son but this gender disappointment is making it hard to enjoy this pregnancy :( anyone else experience this? Any up lifting advice? TIA
