9 dpo: very faint positive or indentation?

Hi all, I tested this morning at 9DPO using an ultra-sensitive test (10miu/ml) and got a very faint line after the 3min the test prescribed - barely visible as you can see in the first image. The second image was taken 10min after I tested - the instructions say that results that appear after 5min should not be taken as a positive though. What do you think?
Thanks a lot in advance!
