Faint line after period?!

Chloe

Hi all, just wanted to get your opinion. Was due on my period around 31st Aug/1st Sept.

10dpo (27th) I did a test and was negative

11dpo (28th) I started to get some dark brown discharge/blood - only showing really when I wiped not much. Assumed implantation bleeding

13dpo (30th-31st) - was dark red then a little brighter and heavier then back to dark red

Today (2nd) - I’ve done a test for peace of mind that it was probably AF (very faint brown today)

Do you see a faint line? Could it be possible?!!!?
