They look like evap lines to me especially if they showed up after the time. Get a pink dye test, first response are good x
They showed up after the 10 minutes, don't trust it, wait a few days and retest
I have had exactly this on clear blue tests before, they went from stark white to this over the course of a few hours, gutting
Evap lines, line is a lot thicker on these tests like the control line if positive, never take the result after the 3 minutes/5 minutes as it makes it invalid x
Looks like you are to me congratulations if u are, id take another in lik 2 days time , keep us updated hope your ok x
