My 5-week-old cockatiel keeps on screaming

I've had Chika for about 3 weeks and recently she's been screaming a lot. She used to chirp all the time but now whenever I take her out of the cage she just screams and screams. I tried to play with her and sometimes she stops but most of the time she keeps on screaming. I tried feeding her some fruits and seeds and stuff and she usually stops to eat but as soon as she's distracted she continues screaming.

This has been going on for a few days and I'm concerned. She stops screaming as soon as I leave the room but continues as I enter it. She doesn't scream when anybody else is with her (might be because I'm the caregiver)

Any idea what's going on? Is this normal or is this something to worry about? What can I do to stop her screaming thing?
