Kicking!!

I am 17w tomorrow! I started to feel little flutters at about 12w! Feel them now and then! Today, I swear I felt a big kick in my lower left abdomen below my belly button! This is my 2nd pregnancy, I do not remember such hard kicks this early, of course it's been 14yrs!! I know it wasn't gas, it literally felt like a kick, it was so hard it startled me!! Could it be? My god, what a strong leg he has already!! Lol
