Should I go to the emergency room?

Ash
Currently 24+1, and I haven't felt movement for about a day and a half. I'm worrying because I usually feel some kicks, and I THINK I've felt flutters but I may have imagined it because I'm thinking about it too much? I know the baby's not big enough for me to feel everything, but should I go to the emergency room tonight if I'm still concerned, or just wait it out and stay worried? I don't wanna waste time in the hospital but I also wanna ease my mind :( advice?
