My first pg, I was pretty small & bump was evenly spread. I didn't put on a massive amount of weight but was told your arse gets bigger with boys & I think mine did. It was a boy.
2nd Pg, I put on alot more weight, my arse got big again & it was a boy.
3rd I haven't put on a big deal of weight & don't think my arse got bigger & its a girl.

But also you should note that there was a noticable difference in the level of exercise I did with each pg & I think that had more to do with how I carried & the extra weight that I did or did not put on.

If you look at my ticker, I am all out the front too & its a girl
