Gender disappointment

Me and my husband just found out via the NIPT test that we are having a girl. It’s our first child and we always just expected we would have a boy first. We had a name picked out and everything. When we both looked at the paper together, he could see that I was really disappointed and I think he’s really trying to stay positive for me. I’m also worried he’s disappointed too. Anybody have any tips to help with the disappointment? I just keep telling myself how glad I am that our baby is healthy, but I can’t help but feel a little sad.
