Serious gender dissapointment.

I've known for a few weeks now that it's another boy but I'm just so sad I can't believe it and feel like I'm not connecting to him I have always wanted a girl but the first two times got boys which I of course accepted and found names for blah blah blah but this pregnancy Is the first without my mother, I never had any sisters, and I lost a little girl at 20 weeks in January. I'm just really struggling I really wanted that mother daughter bond back desperately
