Obsessing over faint lines

keri

My period is dues Wednesday 1/12. I tested Friday, Saturday and Sunday 9,10 &11 dpo. The tests came up with faint lines. But I am obsessing over how faint they are. My doctor won’t see me until I am 8 weeks so I have an appointment on February 7th. Is it normal for lines to be faint ? It’s also hardly showing up on my test strips. Should I be worried ?
