Finding out gender anxiety!

I already have a little boy and I'm hoping for a girl this time. I find out on the 16th....but I'm super nervous its another boy. We are done after this baby (due to my body having complications while pregnant). I'm nervous that if it's a boy I'll be sad and grieve over the fact that I'll never have a girl:/ any advice on how to prepare myself be happy no matter what?

Side nite: obviously I'll still love baby even if it's a boy
