I really really hope you hear girl too, it's such a mixed bag of emotions and hormones and yes...I remember thinking about it day and night!
My instinct was totally off for this pregnancy (35wks) i was convinced he was a girl, felt so rough all day long, before I ate, after I ate..just all day hangover feeling that I didn't have with my first two boys...It hit me like a heavyweight knock out punch when they said boy at 20 weeks..
I had already pictured myself sending out all the texts to friends saying it was a 'girl'..instead i walked home by myself with tears streaming down my face and then feeling so awful because this baby is my baby and he is meant to be with me.
So..I really hope you get to hear girl...but if you don't and it is baby boy #4 and you do feel completely sad..it will get easier and I feel so much better now at 35wks than i did at 20, this board is definitely where to come for support and know that we all understand!
Good luck with the rest of your pregnancy and let us know when you find out!! x
