I am that same exact way!! I am very much smaller with this one that with my son, but I feel sooo much bigger
I think it's because with my son I was all belly. I feel like as soon as I peed on a stick I was showing. It was all in the front and there was a lot of it
With this one I feel it in my butt, my thighs, my boobs and of course my belly. I just feel like I am expanding outward everywhere
I definitely feel your pain
