Sleep routine help

So im noticing my newborn will sleep a good 4-5 hours around 2-4 or 5 pm but when it comds to the morning and night she only sleeps 2-3 hours and yes i get super sleepy. But is that bad for her sleep routine or thats normal? For being a 3 week old baby? Should i try keeping her up during the day and have her sleep nights? Or just let her sleep?
