My 5 week old baby was born with purplish inner lips. over the weeks its seems to be getting darker. should i be worried that she isn't getting enough oxygen?

Evaluation: Very often signs of congenital pulmonary or cardiac disease appear in the first weeks of life. I would also suggest checking her nail and skin color. Poor growth and sweating during feeds is another concerning sign. Please see your Pediatrician soon and a virtual inbox photo may also be uploaded to Healthtap for review and consultation.
