less movement

Alondra
I'm 27 weeks. I'll be 28 weeks on Tuesday. 
I was walking around the fair for about 4 or so hours and now I don't feel him as much. 
I tried ice water, eating something sweet, poking, jiggling my belly but he doesn't wanna wake up. 
I have a slight cold as well so I'm not sure if that could affect anything 
I'm getting my vaccines tomorrow and on Tuesday I have my monthly check up. But I'm still concern about him not moving much
