feeling baby.. so soon

I'm 12 weeks and some days now. but recently started feeling baby move (I'm almost 100% positive) is this too soon? This is my second pregnancy and I was further along with my first before I felt him. Also I'm not talking about big movements, where I'm feeling from the outside. but these are small, light, butterfly, bubbly movements (not gas, as I've also had gas, but gas is a stronger feeling)

Anyone else feel it so soon or am I just crazy?
