Pregnant or no?

** it's not an evap line. Evaps do not have color & the line on this test is pinkish.
My friend took this yesterday. It didn't show up until a couple of hours after. She is on birth control and is supposed to start her period a couple days after she takes the green pill but she started a whole week early and it was super light but then when she started the green pill she started again and again it was light.
She took a blood and urine test today and I'm guessing both were negative because she said she wasn't preggo. But how is that possible?
