What could this mean?

Melanie • 33 Mother of 3 👩🏻👧🏻👧🏻🧒🏻

Ok so this is my sisters results. She’s only been pregnant once but sadly miscarried 😔 and has been ttc for about 3 years. She took this test 6 days after her period ended..(I know it’s kinda early) but she started spotting which wasn’t her normal and decided to test to see what was going on. Has anyone ever had this happen to them?
