Apparently if your bum grows initially you're having a girl while if your boobs grow you're having a boy. This held true for me and my sister.

I'm having a girl and i'm all out front, big round bump, although i have put some weight on my backside and legs. The sonographer said he as 110% positive she as a girl, hope so as i have spent a fortune on dresses lol

The test was wrong for me said 65% boy.

The boob thing marley mentioned works for me though, i have only gone up one cup size... and my ass has definately got bigger

I must be having a girl because I've noticed the last couple of days that I am SO wide across my hips and butt now.

The test said I have 45% chance it's a boy, and 54% change it's a girl.

Hubby has a gut feeling it's girl. I don't want to try to guess because I don't want to get my heart set on anything!! We will be thrilled with either though!! My mom says it's twin boys!

this is the first test that I've done that has got it wrong! Says I have a 56% chance of a girl, but he is definitely a boy.

I've had a lot of people say I'm having a boy because I'm carrying small. I'm actually quite impressed, everyone who has tried guessing based on my belly has got it right for whatever reason!
