Yep, I think you can. This is my third child also, and I have had the same "rolling" feeling, at 12 weeks, and have felt little flutters even earlier.
I'm 12 wks and have noticed fluttering for about 2 weeks now that is getting stronger. I have even put my hand on my tummy and pushed in a little and could definitely feel it!
im n same boat i am 12 wks and im feeling the little fluttering and it started wen i was 10 so yea i think it is poss!
I think 10 1/2 weeks is still pretty early even for someone who has had previous pregnancies. From what my doctor has told me, the baby is sooo small and barely weighs more than a feather at that point, that it would be pretty difficult to feel it move. But, it would be cool if that is what you felt! :) I am sure though that in a few weeks you will be feeling the baby while the rest of us first timers are dreaming for that day :)
I had a similar experience today while driving. It felt like the baby did a somersault or something in my tummy. I was like "umm...isn't it early for this??" but I don't know how early you can tell. Odds are it was gas...but I like to think my kid is just advanced. jk :) This is my first though so it probably was just gas or the uterus stretching.
From what i hear is that you start feeling it earlier and earlier with each pregnancy. But 10.5 weeks does sound a bit early
