Lets say you take a pregnancy test at 11DPO. You look at the test after 1 minute and there is no line, so you get in the shower. By the time you get out of the shower, there is a faint line (after 15 minutes). Is this a true positive? Or is it possible to get a false positive after that long?

1-3 minutes.
Looks like I'll be testing again tomorrow or the next day.
