Baby not moving a lot 26weeks

Cheyenne

Should I be concerned if the baby was pretty active and the past 2 days she hasn’t been as much as normal just a kick here and there when before it was all the time i even drank cold juice and ice cream which normally gets her going I just had a ultrasound the day before she calmed down and everything was fine .. idk if I’m over thinking it .. my lower abdomen is also a little sore
