Gender feeling? Feeling guilty!

Is anybody else so convinced over their unborn baby's gender that they can't even consider a different gender? 
With my first I felt she was a girl and I was right. 
This time I'm soooooo convinced it's another girl even though my MIL is convinced it's a boy and a telling me
I am wrong and I will feel guilty when I am proved wrong, but my issue is I can't even consider a boy because even when I try my gut is telling me it's a girl! I'd be more than Happy is baby turns out to be a boy it's just my true feelings. Does anybody else feel this strongly xx
