This is my first pot here. I was using a different app but every time I post I get no replies! So i thought I would try my luck here. Im a FTM and I had a little bit of a pot belly before I got pg. I know that my uterus inst that big yet but my stomach is huge. I was getting bloat that would go away in the morning but now my tummy is round all the time. It doesn't go away. Do you think that as my uterus is starting to move up its pushing out my pot belly making me look more pg than I am? I can suck it is just a tiny bit but its super uncomfortable!                 
                             
        
Re: 13w+4 tummy is so big!
Bloating only enhanced it.
Also, depends on your height. Shorter torsos lack the space for things to move around, so things get pushed out more easily, also muscle tone plays a role too.
At 13 wks, your uterus is JUST starting to move out of the pelvic cavity, but you may notice some growth this early, but not everyone will notice.
