Fault?

Sarah
Hi girls. Looking for some advice on this test and wondering if this has happened to anyone else. 
​I took a test at 12dpo which gave me a super faint line. Like ridiculously faint. AF is due today and last night I swore she was going to turn up. But still no sign this morning so I took another test. 
​However look at this...the dye before the control line came straight away and didnt disappear. It's still there now. Do you think it's a faulty test??
