odd question

My son is 5 weeks and I've had those weird tummy flutters that are in beginning of pregnancy since a week or so after having him. Is it normal/common to have that weeks after having baby? If so how long can it last? (Sorry if its a weird question or doesnt make sense i dident know how else to explain.)
