or try going to pee on a stick.com they show you the differences between evap lines and positives for the specific test you are using.
if it really was a faint line, a faint is still a positive. I've had two faint positives now & I'm testing again tomorrow. Wait a day or two & retest or buy a more sensitive test. G'luck
Clearblue tests have blue ink and are well known for showing an evap line like your aunt said. I used to get those ALL the time with that test. Best thing to do is try using a different test like a First Response or even the dollar store kind since they are both super sensative and neither ones have the blue dye. You might also want to try a EPT pregnant/not pregnant test that would give you a sure answer. Best of luck I hope you get your BFP! :)
