Baby moving a lot less

Erin
I'm a FTM. I'm 34 weeks. Today I've only felt my baby move a handful of times and nothing in the last couple hours. I tried orange juice and laying on my left side. I'm going to try a cold glass of water now and I guess call L&D at this point. I'm just stressing and wanted to see if you all have gone through this or have other tricks I can try. Thanks!
