Faint positive 7dpo, BFN since

[bbkw]

Hi all,

I have been trying to conceive since May. I fell pregnant in August and had a miscarriage at 7 weeks, I have been TTC since.
I am currently 11 dpo. I took a test 7dpo (early I know) and I got a faint positive, see picture.
I was so excited and expecting the line to get darker and progress, however, I have had BFN since.
What could this mean? Could my faint positive have been a nasty indent line?

I have also been getting positive OPKs since 9dpo.

Thank you

Sounds like an indent. Impossible to get positive at 7dpo

Definitely possible, I had a faint line at 7dpo last month
then 3 darker pink tests on 8dpo then by 9dpo they went negative and my period came when it was due so I assumed it was the start of a pregnancy that didn’t manage to stick
ive also had a faint line at 7dpo with my DS
