FRER, 12 DPO

Okay ladies. This FRER I took yesterday at 12 DPO. At 3 min there was a super faint line (sorry didn't take a pic)that I thought looked like an evap. Over the course of the day it kept getting dark and definitly is pink. Do you think it's positive? I'm going to wait a couple days to test again. Confused!!!!
