I'm 24 weeks now and have been feeling the baby move for maybe 3 weeks now. At first it was very low down and quite weird/uncomfortable.. a couple of times really strong like she was thrashing about 
. Lately though it's changed a bit.. there's still movement but it's higher up and seems more "muffled" (TBF I do have more fat in that area of my tummy..). Does this sound normal? The advice I've seen seems to suggest that movements should become "regular" by 28 weeks but so I don't know if changes early on are a problem or not. Thanks!
