Cluster feeding

My baby is 2 weeks old and wakes to feed every hour. Sometimes he will go longer but the last few days it’s been every hour. Is this normal? Could I not have enough supply? When he pulls away there’s always milk around his mouth. He has also been fussy after feeding burrowing himself in my chest making grunting noises and curling up in a ball... could this be gas?

He has many wet diapers a day and burps after feedings most of the time... sometimes he doesn’t but I keep him upright for 10-15 mins after feedings.
