less movements for 2 days

Hi mommies, im currently 22 weeks + 7 days now. Starting about week 20 to 21, i felt my baby move almost on daily basis although its just little movements like flutters. However for the past 2 days, i havent really felt anything... so i be worried? I know in third tri then will feel more obvious movements but its weird why i felt movements everyday except for the past 2 days. TIA!
