Hi i had nose bleeds with my 1st and i had a baby boy. I think it doesn't have anything to do with gender x
I had a nose bleed but that's mainly because my 1 year old jammed her finger into the deepest crevices of my nose and scratched her way out in the amount of time it took to blink lol. Not much help but I hear they're common.
Yes I have been having nosebleeds too. Just got one on the airplane yesterday. It was so embarrassing! I'm also not finding out the gender, so I can't help you with that though.
