Hi, I know it will be hard but try to wait another 2 or 3 days before testing again so that you will have a more accurate result iykwim?
Not wanting to dampen your spirits but with the digital hpt's, they usually show 2 lines inside even if it's a negative. They arent meant to be pulled apart. Also i think thay are 50mlu.
If you are only 9dpo it's probably still too early for it to show so my fingers are crossed for you
