She went 4 hours 🤯

Im only 3 weeks pp and baby just went 4 hours between feeds. I know I should be greatful this once but 1 I'm slightly nervous about that and 2 I wasn't even engorged when I woke up?! Which is crazy because I typically feed every 2-3 hours and feed baby as well as get 4-5 oz in my haakaa, this time I only got 2 off the opposite side.

Should I be worried about either problem and or what should I do??
