Help! 5 week old over sleeping

Kelly

Baby was 5 weeks Sunday and slept for 6+ hours tonight 10:15ish until 4:20 when I had to wake her and she had no diaper, she had plenty earlier and I can’t keep her awake. I nursed her but she isn’t really eating, no fever. I changed her after one side and had a little pee and just a dot of poop. Put her on other side for 5 min if that and she is out like a light. Tried burping her changing her again and she just wants to sleep. Should I call pediatrician? My breasts aren’t engorged and seem softer after she ate but I’m not sure what is going on. FTM. I do see lactation at 9 AM.

What should I do I’m freaking out.
