I think you're pregnant

At 8 dpo you would expect it to be very faint, very...very faint. Implantation only occurs 4-7dpo and then you allow another couple of days at least for the implanted embryo to start producing enough HCG to give you a positive test. It will start off faint and get darker over a week or so.

Actually I remember testing at 9dpo with my son and got a negative...kept testing because I knew I was pregnant and it took until 11dpo to get a very faint positive.

Confirm are quite reliable, I think they measure 25 miu.

Congratulations!
