I read somewhere that the way you carry is alot about where your bowels get pushed to as your uterus grows.

If they get pushed up and to the back you tend to look more like the basketball/all out the front or all baby.

If they get pushed up and out to the sides you get the more rouned out to the sides kind of look, or maybe like when someone's said to be carrying to the back.

And apparently the pushed up and out to the sides is a better option..more room in the bowel and less likely to be constipated, compared to if they're a bit squashed up behind the baby

I'm only 2nd tri but carrying more to the back & out the side kinda look
