My baby barely moved today

Hi mummies! I'm in my 27th week of pregnancy (first pregnancy) and I barely felt my baby's kicks today! Should I be concerned about this matter? Ps: I started to feel my baby's kick as early as my 15th week of pregnancy. So yes, I do know my baby girl's kicking routine by now. Its odd to not feel her actively kicking today. #1stimemom #firstbaby #adviceplease
