Pooping problems


My week old baby has recently had frequent poops- had a poo in her nappy every feed, which was about every 3 hours. However the past day, she’s gone from having one every 3 hours ish, to 3 in the whole day, is this normal? Also yesterday (25th) I had to call an ambulance due to her being unresponsive, and he checked her over, and she began crying when he pressed her abdomen, and he thought something was up, however the Pediatrician said everything’s fine. I think her tummy feels quite hard.. What shall I do? Am I over thinking?
