Congratulations msadelaide looks like a BFP to me. And at 9DPO you would expect it to be that faint. My lines looked the same that early and gradually got darker. I wouldn't rush of for a BT for another few days at the earliest cause I would guess its your BHCG at the moment would be around 10. A friend of mines looked like that at 10DPO and her BT showed a BHCG of 8. Dr told her she wasn't pregnant but of course she was it was just super early.
