Anterior placenta 25 weeks, baby kicks lighter

For the past couple weeks the baby has kicked me hard and I’ve felt him pretty good in the mornings and evenings and some during the day. This last week he may have changed positions because I don’t feel him kicking my bladder or cervix and the kicks are lighter and less frequent.

Is this something to worry about or is it possible he moved up and is kicking my placenta? I hate freaking out about this but don’t went to ignore something serious
