Can I get support form the midwife with gender disappointment?

I found out this week that we’re having a boy. I’ve tried to accept that my dream of a little girl isn’t going to happen. I’m still finding myself crying and I feel so disconnected from him. I’m not sure if there’s any help available in the U.K. for this kind of thing? I have my 16 week app in a few days. Should I mention it to the midwife then? Or keep it to myself?
