Confused about bump?

[Chickenfillets]

I'm 21weeks today. When I lie flat on my back my bump is quite small and low down. But when I stand up I look huge and have a full on round bump. Is this normal??

Yes

Yep! Changes shape depending on how you sit / lay / stand

I also found some days it looks small, others big!

Totally normal ... !! You will find furged on it quite often changes shape completely as little one finds different positions ... One of mine lay transverse at 35 weeks with head on one hip and fwet on the other laid straight across ... my midwife could tell from across the room as my bump looked like a really bizarre rugby ball :)

Im 30 weeks, and have only just started noticing a bump when lying down! When standing up its very noticeable, but I could probably still hide it when lying down if I wanted to.
