Fetal movement 22w4d

So baby girl has been very active up until yesterday and today, she's barely been moving and when she has it's been very faint feeling...in leaving on a trip to Vegas in 2 days and I am trying to be positive but again I'm afraid of flying and I'm afraid of something being wrong and not knowing it while we're gone...r these movements or lack of normal do u think? Help a FTM out!
