Showing at 8 weeks?!?!?!

I’m 8 weeks pregnant with babe #2 and for the past 2 weeks I’ve been “showing.” I know it’s really early and people chalk it up to bloat, but this isn’t that. I can’t sleep on my stomach anymore because I feel like a hard ball in my stomach and it hurts to sleep on it. I’m a bit on the chunkier side, but not overweight by any means. When I go to “suck it in” only a bit goes in and I’m left with this bump, that even when I was extremely bloated at 4 weeks, I could still suck it all in. With my daughter I was really tiny and didn’t show until almost 6 months. I’m just so confused. Sorry for the book, but similar experiences would be appreciated ❤️ TIA😌
