Faint positive or evap/indent?

I am at 10 or 11 dpo. Had some weird spotting 36 hrs, which is still going. Not even enough to wear a pad or so.
Tested with urine that was a rather pale yellow, because I drank during the night. 

But there is a second line. Do you think this might be it or is it evap or indent? 

It had color and it doesn’t go away if I dip in water....
Obviously ttc

thank you!!!
