no fetal movement for a day

i’m 22 weeks pregnant and 2 days my baby was constantly moving at night time and when i laid on my back. he has not moved i tried playing music last night, drinking cold stuff, eating and nothing. i’m concerned since he didn’t move at all yesterday and today i think i felt two kicks in the morning but i’m not exactly sure. i know what his kicks feel like so those didn’t feel that strong. it’s almost 1pm and not much movement at all. i want to call my doctor but i’m afraid they won’t take my concern serious since i’m only 22 weeks however my baby had been moving constantly prior to this
