I have felt like that before

It does for me. Specially during the day its much smaller and by the evening its huge. And yeah also like @lovelyadre said.

Lol yeah I woke up today and was like Woah where did my belly go?! Then I ate and he moved around and I looked again and there was my huge belly haha

I woke up and my stomach look really small an I was worried that something happened to my baby in there that is like compressing him 😝😁

Yup. It's just depends on how baby is positioned.
