Fetal movement...worried FTM

Elizabeth
I need some advice or opinions ladies. I'm 24 weeks this week, and I've felt the baby move regularly and actively for weeks now. Yesterday morning I woke up just feeling kind of "off" a little jittery, abnormally fast heart rate, almost like I drank a bunch of caffeine , which I don't drink at all. I went to work and eventually felt better but now I haven't feel him move since, and I usually always feel him at night and in the morning when I'm not active. I'm not sure if I'm just freaking myself out, or if I should call my doc when they open and see about going in Maybe just to check on him?
