Reduced movement

Every morning I am awaken by lovely movements from our little boy. Until today.... I woke up, was able to do my full morning routine without a single kick... I am 36 weeks + 3 days along...

Drank some juice.. laid on my side.. and started the clock... it took 15 minutes before I felt one very soft kick... then nothing...

My husband says to stop worrying about. That he's probably just sleeping...

But I feel off. Like something is wrong... having some food and a small cup of coffee now.. see if our baby wakes up..

Anyone been through this? When should I worry? Am I over reacting?
