Anterior Placenta and Change in strength of kicks

Hi, i am 27 weeks today and have an anterior placenta. Just wondering if others have experienced a change in strength of kicks? Some days i feel definite kicks and then the next day it will be back to flutters that are very faint. Other friends seem to be able to tell when its hands and feet bit i cant tell what body part is poking and only ever feel it low down in my pelvis, never at my sides and very rarely at the top. Any thoughts, advice or own experiences would be greatly received. TIA
