28 weeks no movement

I am 28 weeks and 3 days. Baby has been consistently active for a long time now everyday always active i always say she never sleeps. Yesterday i was with a friend and figured a hadnt felt her due to being distracted. Once my boyfriend got home from work it was late and we went to bed, i still hadnt felt her. I got a random sharp pain in my stomach really low like a cramp but it lasted for about a second and never came back and had no other symptoms. This morning i took a bath , played her music, ate a good breakfast have been drinking water and i still haven't felt her. My stomach feels harder than usual. I feel more light flutters like when i first started feeling her move but absolutely nothing compared to what i usually feel every single day and its not in her usual spot i feel it very low. Should i be comforted with the very light flutters or concerned with the lack of movement?
