I just don't understand it. The size of my bump would always fluctuate but it was getting to be so obvious that DH and I decided we'd have to come clean (we ideally want to wait till after 20 week scan) with some people. So at work I told a couple people who had already joked about my weight etc.
The thing is it's usually fine most of the day and when I've been sitting so had managed to keep it under wraps (I'm almost 18 weeks) but on waddle home at night it's always real big to point where I get the nice smiles from other mums, people give up their seats, can't button cardigan... you get the idea. BIG. To the point where there's been tantrums about how big I might get if I'm already this big.

So today is, well, scary. It's like I'm back to my original shape. Seriously. I know the bump can change due to water retention, wind, etc but this is weird. Such a huge difference. And especially annoying given I had just told people I wasn't comfortable telling because it was so obvious.

Should I be worried? Has anyone else experienced such a dramatic change? Wish I had pics so you could see for yourselves.

At 18 weeks I wouldn't worry.. The baby is still small enough to sit right back which will reduce the size of you're bump.. My bump used to disappear all the time intill I got to about 25 weeks and then it was just there all the time.. And even now it sometimes looks smaller on some days.. It all depends on how their sitting and how far forward they are... Like I said though I wouldn't worry

Hey this happened when i was around 17 weeks but then i woke up with a proper bump. Maybe what you thought was bump was bloat, because i always thought my bloat was bump and i could suck it in but now its impossible for me to suck it in. Or maybe your babys hiding somewere

From personal experience: My bump looks the smallest in the morning. Even in my first pregnancy at 8-9 months I'd look like I was 6 months in the morning. It really makes me uncomfortable too bc I know the baby is the same size but does he/she have any room in there when my stomach is deflated? lol. I know its nothing to worry about but its weird though.

You're not alone...I'm almost 17 weeks and I feel like my bump is diminishing. Like you I 'popped' early, and now it feels like I have a 'shrinking' bump. I have been trying to not worry about it, but like you I do have some concern.

same here. sometimes it is bigger than other days. and very small in the morning it scares me.

Mine varies too, huge one day, non-existent the next! x

its probably where your baby is lying as someone has said x

Mine has done this today! I still have a bump just LOTS smaller than yesterday lol., I think baby is sitting in my back tho, as I am getting achey back and I am feeling kicks all at the front! I am sure it'll pop back later and I will be huge again haha!

I get this too..
