God told her?!?!

My mother-in-law said she asked God if we are having a boy or girl and he told her a boy! But everyone else thinks girl, my husband had a vivid dream of baby girl and I feel so so strongly it's a girl and all old wives tales point to girl BUT only God knows right?! It just surprised me but will find out next week Thursday at ultrasound. 
Has anyone else had someone say something like this? I mean I don't know if I should believe it? I believe in God but it can't be that easy for Him to just answer a question right away like that!
