Haven't felt him move in a few days.

Anyone have any suggestions on how to get a baby to move? I'm 24.3 weeks and I haven't felt my baby move in maybe 2 days. I have been REALLY gasey so sometimes I THINK I feel him move but then I just pass gas after I feel it. When I feel what i do it doesn't feel like it did when I have felt him move before. I have tried pickle juice to get him to move, I have tried the drink a glass of water and lay on your left side. Sometimes he lays low near my pubic bone, sometimes when I feel my stomach I don't feel a hard spot anywhere at all like I use to (either to the left lower or the right lower of my stomach). I'm starting to get a little worried but I don't want to go to the ER and sit and wait 6 hours like I did before (that was when I was spot bleeding in the start and found out I have a subchronic hemorrhage).
