Newborn sleeps for )+ at night

My baby is 5 weeks old now but i always have to wake her up at night to feed her after 5 hrs max, as i forgot to set my alarm and slept my baby slept longer than that and still had to wake her up for feed and throughout the day sometimes she has short naps instead of longer once, does anyone else have long sleeping baby at this age?

She sometimes barely wants to sleep during the day and then she can sleep almost all day similar pattern to when she was in my tummy. Is there something to be worried about?
