So I'll be 17 weeks Thursday and I go December 6th for my gender ultrasound, I desperately want a girl because I have 2 boys, to help with my sadness with gender disappointment i did a sneak peek at 8+1 weeks and it said girl, i have been so confident but now the close December gets I'm getting scared, should I be worried my test was wrong? I need someone to talk to lol
