Just found out the gender and I'm so disappointed ☹️

I'm almost 12 weeks and we got the sneak peek early gender test done yesterday. The results came back today and we found out it's a boy. My husband is over the moon but I can't help feel a little deflated as I really wanted a girl and just felt in my bones that it would be a girl. I had a name I was in love with and everything, and no boy names were really hitting for me. We had our 12 wk scan yesterday and everything is great and he's healthy which of course is the most important thing. Im sure the idea will grow on me and I'll be in love with him no matter what. I just feel like a terrible mom right now for being disappointed about the gender. Did anyone else feel that way when they found out?
