My baby not really moving 😣😣

Stephanie
So I know they say that the farther u get in ur pregnancy , that u feel less movement . I'll be 33 weeks on Friday . I'm very short , only 4'10 . My baby is usually very active at night . But lately , as in the last couple of days . She has not really moved much . I can drink a cup of Kool-aid or eat something sweet an she will move somewhat . Not like she used too . Is it just bc she doesn't really have anymore room to move ?? I'm not having any pain or cramping . I checked her heartbeat on my fetal doppler an it was 142 . I have a ultra sound appointment tomorrow morning . Hopefully everything is okay . Is anyone having the same issue ??
