Husband doesn’t want a daughter..

So I’m having this internal problem with my husband that I haven’t really chosen to voice. My husband really wants a son. And doesn’t acknowledge the fact that we could be having a girl. Every time I bring it up he says some thing along the lines of “don’t jinx it”. And I know he will be really disappointed in me and the baby if it turns out to be a girl. I don’t know what I’m going to do if it turns out to be a girl. I’m scared he won’t be excited about the pregnancy anymore and will just lose interest. Makes me really sad that he’s so dead set on a boy that having a girl would be disappointing. What should I do or say?
