Bump has got smaller!

I'm 24+4 weeks gestation, and my stomach looked really big last week (as though I'd finally 'popped'). It also looked like I was carrying high rather than low. A week on... I am back to how my stomach looked at 20+ weeks. Carrying low and not much of a bump! I still feel regular movements so I'm not too concerned about baby's wellbeing (he likes to kick-attack me when I'm laid in bed lol). But has this happened to anyone else? I'm slightly disappointed as I really loved looking bigger!
