BFP turned to BFN before 15 mins - is it positive or negative?

[user7654321]

So I did a Boots own early response test this morning (i'm approx 10DPO, AF due this Friday/12th). There was a fairly faint but definite pink line, which disappeared / turned to a VERY faint grey after 10-15 mins. . Will test again tomorrow!

Oh @user7654321 it's so stressful isn't it - fingers crossed for your bfp

Hope you get the outcome you want :)
