6 weeks post op w/ odd bulge

So something strange has happened to me tonight and I can't find it anywhere on google or perhaps I'm just not typing the write thing or using the correct terminology.

Ive just hit 6 weeks since my gastric sleeve. Recovery went really well but I'm still trying to learn what I can and can't eat and what my limits are,sometimes throwing up.

Tonight I had home made gnocchi, I didn't force myself and I ate probably about 10 (no extra ingredients, just sauce) and I ate it over two hours, so it wasn't consistent with maybe two sips of water in between.

I've now realised while getting changed is my stomach is almost bulging out, so I hope is my stomach anyway... It's like a big lump, on my left side where my ribs are below my breast. Here's a photo. I'm slightly worried, usually things that have happened for example 3 week stall, I could find a lot on it in this forum but this one I couldn't find anything

hope it just means I over ate, or just something new I haven't notice in my body - I don't know.

Sorry the photo isnt great, wouldn't really show up in pics
