Wet diapers??

My baby fell asleep about 1130 last night. I changed his diaper right before putting him in his bassinet. It is the first time he has slept 6.5 hours. So happy! BUT he woke up with a DRY diaper. I’m so not used to this... he regularly has wet and dirty diapers very frequently/normally. I realize he slept the most he has ever slept in a long stretch and didn’t wake up to nurse. But is still bothers me he had no output what so ever. Is this completely normal??

He is 6 weeks ☺️
