WEIRD abdominal sensation at 6 weeks

Ma

I am 6 weeks 3 days and I got the weirdest sensation. No pain or cramping, but on my lower left abdomen (like very close to my hip bone) it just felt like something popped out and was protruding!? It felt like I needed to push it back in?! I'm thinking it's just the loosening of my muscles and all that jazz, but it was the weirdest thing ever! It's gone now. Anyone else experience anything like this!?
