Indent or maybe faint positive??

Hey ladies..wondering if I can get some input. Yesterday at 12 dpo I started spotting..2 days early but I still think its just AF. But today I am feeling super tired, headachey, boobs hurt and this is unusual when AF (Aunt Flo - menstruation/period) comes usually all that goes away so I took a test. Not familiar with this brand but what do you think? Should be darker If it was a true positive right? This was taken at 2mm.
