Is this normal? - sleeping

So my 7 week old has just woken up. She has slept 11 hours…. Woke up at her usual time but fell asleep 2 hours earlier than normal….. should I be concerned??? Thank you. Note - she active sleeps ALOT and I kept waking up to check on her throughout the night…. Should I be waking her??? She’s feeding/ going to the toilet as normal and she usually stays awake most of the day.
