Are these flutters?

[Lilybow]

I'm 16+5 weeks, first baby, and last few days when I'm sitting down or standing still and eaten/drank something my stomach feels like it's all of a sudden being flipped or something else. It's really short and quite sharp so bit uncomfortable. Then it goes.

Not describing it well as hard to describe. Could this be flutters?

My first feelings were at 16 weeks and I felt like I had a butterfly in there. No pain though

Yeah I think its more uncomfortable than pain, or maybe because it's such a random sensation it takes me aback a bit
